Discovering Applications and VMsThe first step to protecting your data is to have Actifio PAS discover it. When you discover applications, Actifio

PAS identifies the various data resources on the host and presents them in the Actifio Desktop. Then you can

protect them, and eventually recover them if needed.

Actifio PAS discovers VMs by querying vCenter using VMware APIs. For automated discovery of other

applications, you use the Actifio Connectors. The Actifio Connectors are software components that connect the

Actifio Desktop to Windows, Unix, and AIX hosts. Procedures for installing the Actifio Connectors are in the

Actifio PAS Documentation Library, reachable from the life-ring icon in the lower right corner of the Actifio

Desktop.

If an application is on a host that cannot be reached by an Actifio Connector, you can create the application

manually with the New Application feature on the service menu.

Application discovery and creation are detailed in Discovering and Creating Applications, Groups, and Virtual

Machineson page 7.

Introduction

Protecting ApplicationsWhen you protect an application with Actifio PAS, you apply a policy template and a resource profile as

detailed in Chapter 3, Protecting Applications.

The Protection Options on the App lication Manager Protect Tab

Before you can protect applications, you must:

Discover them, as detailed in Chapter 2, Discovering and Creating Applications, Groups, and Virtual

Machines.

Have a policy template and a resource profile in a Service Level Agreement (SLA). You develop SLAs

with the SLA Architect, detailed in Planning and Developing Service Level Agreementsin the Actifio

Documentation Library.

Restoring ApplicationsWhen you restore an application with Actifio PAS, you follow the procedures described in Chapter 5, Restoring

Protected Applications. Actifio PAS allows simple, fast access to point-in-time images of your application data.

The Restore Options on the Application Manager Restore Tab

About In-Band and Out-Of-Band Applicat ion ProtectionApplications can be in-band or out-of-band. Even a discovered application on a VM can be in-band if the

application is entirely resident on physical mode RDMs exported by Actifio PAS. A discovered application on a

VM is not in-band if its data stores are in band. The type of backup performed depends on the collection of

volumes that the application resolves to at the backup time. If any one of the volumes is out-of-band type, the

whole backup is performed out-of-band. If all the volumes are in-band, an in-band backup is performed. When

an in-band backup is performed, all volumes are snapshotted at the same time.

When you set up an in-band VDisk, you:

1. Create a virtual disk.

2. Map the virtual disk to the ESX host/cluster.

3. Use vCenter to create a data-store on the virtual disk.

4. Use vCenter to create virtual machines on the data-store.

Discovering ApplicationsYou can discover applications on physical hosts and on VMs. You must have the 'Host Manage' or 'Application

Manage' rights to discover applications.

Discovered applications are those that are identified by the Actifio Connector on a host. This includes:

File systems on Microsoft Windows and Linux, including local drives and mapped NFS/CIFS shares

Microsoft SQL Server, Microsoft Exchange Server and Microsoft Share Point Server on Windows Oracle database on Windows, Linux, and AIX

vCenter hosts

Note: Only CIFS shares that are mapped with the Reconnect at logon option on the host will

be discovered.

Note: For Oracle databases, make sure that the oratab, tnsnames.ora, and listener.ora files

contain entries for the database that you want to discover.

To discover an application:1. Open theAppl ication Manager.

2. From the service menu, select Discover App(s).A list of all hosts appears:

Discovering Applications on a Host

3. Select the host that includes the application you would like to protect.

4. Click Discover. The navigation pane lists all the applications attached to the selected host, including

applications residing on out-of-band storage, as soon as they are discovered.


13/56

9



Discovering Virtual MachinesThe prerequisites to discover a virtual machine on an ESX server/host are:

Have the 'Host Manage' right to find a virtual machine.

Add a vCenter and an ESX server/cluster as hosts separately as described inAdding a Host section.

When the ESX host has virtual machines already created, add a vCenter or ESX server/cluster as hosts

separately as described in Configur ing Actif io PAS with the Domain Managerin the Actifio DocumentationLibrary. You can discover and protect the virtual machines associated with a vCenter via an ESX host or

cluster. These VMs are protected using VMware snapshots to get a point-in-time image (application consistent

under the right conditions). The data stores that the VMDKs live on may be in-band or out-of-band.

To discover a VM:

1. Open the Application Manager.

2. Click Discover VM(s)...from the service menu. The Discover VM(s) window appears.

Discovering VMs on a Host

3. In the Discover VM(s) window, select the vCenter you added as a host earlier. Click the vCenter. The

Discover VMs window discovers and displays the ESX host/clusters managed by the vCenter.

4. Click an ESX server/cluster. If there is an agent on the vCenter server, then the ESX server and its

virtual machines are listed. If not, then only the VMs are listed.

5. Select the virtual machines that you would like to protect.

6. Double-click Discover. The virtual machine is added to the list of virtual machines atAppl icationManager>Appl ications by Type > VM.


14/56


10


Actifio PAS handles multiple VMs with same name using an unique identifier (UUID) and a friendly path.

These details can be viewed by hovering over the VM in the left pane or in the details section. The

friendly path comprises of the VCenter name, Data Center name, and path to folders of the VM as shown

below:

Differentiating mul tiple VMs with UUID

After discovering the virtual machines, all the ESXs that can be seen from that vCenter and the

discovered VMs are added as hosts under the Hosts page.

Note: Only one password can entered for VM discovery. If the vCenter host has CIFS and/or NFS share drives

that require passwords that are different from the vCenter password, they will not be discovered.


15/56

11



Creating Generic ApplicationsA generic application is a collection of in-band virtual disks. Generic applications are snapshotted using

consistency groups, and you get all VDisks frozen at the same point in time.

Every generic application has an associated host where you can run pre- and post-scripts. To run scripts, you

must provide the user credentials for the host, and the host has a connector that has been discovered.

To create an application on a host that does not run the Actifio Connector or to name an application on a hostas required:

1. Open theAppl ication Manager.

2. From the service menu, select New Application....The Add an Application window opens:

3. Enter the name of the application in Enter a Name.

4. Click the appropriate application type such as VM, Oracle, SQL Server, or File System. Alternatively,

enter the application type.

5. Select the host on which the application is running from Select Host.

6. Click the host to view the virtual disks attached to it.

7. Click the virtual disk you would like to assign to the application. Repeat this step to attach all the virtual

disks that are associated with the application.

8. Click theAddbutton.


16/56


12


Creating a GroupA group is used for ease of management to apply a common policy to all the groups applications. Mount, clone

and restore operations are performed on the backup images of each application in the group individually.

To create a group of applications to manage the group using a common policy:


2. From the service menu, select New Group...The Group properties window opens:

Creating a Group

3. Enter a name in Group Name.

4. Select an application by clicking the +sign displayed against the application. Alternatively, you can add

all applications to the group by clickingAdd A ll .

5. Click Save.


17/56

13



Creating a Consistency GroupYou can create a consistency group to back up application data of all member applications together to preserve

consistency of data across the member applications. In addition, you apply a common policy to the members of

a consistency group. Consistency groups are applications that are a collection of discovered applications from

the same host.

When creating a snapshot of these applications, Actifio PAS resolves all of the applications into a collection of

volumes. If all of these volumes are in-band virtual disks, then the consistency group is snapshotted at the

same moment in time. If any one of the volumes is not in-band, then the consistency group is backed up as

out-of-band application, and the constituent applications are self-consistent, but not at the same-point in time.

To create a consistency group:


2. From the service menu, select New Consistency Grp.

Creating a Consis tency Group

3. Select an application by clicking the +sign displayed against the application. Alternatively, you can add

all applications to the group by clickingAdd A ll .

4. Click Save.

Note:Adding generic applications, virtual machines and Oracle Applicat ions within a

consistency group is not allowed.


18/56


14


Deleting an Application/VM/Group/HostYou can delete:

Applications, VMs, groups, and consistency groups that are discovered but not protected.

Protected applications, VMs, and groups after unprotecting them (disassociating the SLA).

Hosts, after un-mapping the VDisks associated with them.

Note: You cannot delete local applications, VMs, groups, or hosts. Remote objects that appear in the

Application Manager under the Remote category should be deleted from the remote PAS cluster.

To delete an application, VM, group, or host:


2. Click the App, VM, Group, or Host filter tab from the top of the navigation pane.

The Application Manager Navigation Pane List Filter

3. Select the Application/VM/Group/Host to delete.

4. From the service menu, click Delete.

5. Click Yesin the confirmation dialog.

The application appears as an orphan in the navigation pane under Orphan. You can delete a resource

profile or a policy template only when the resource profile or policy template is not used to protect an

application. You can see an application in the orphan section only if there are any images corresponding

to that application.

Note: Deleting an application or the protection cleans up the dedup-async related images (if dedup-async is

configured for that application). If any stale images are left out on the PAS (usually due to a remote cluster

unavailability), in the left bottom menu list, you will see an operation called Cleanup dedup-async. See

Deleting Failover, Test-Failover, and Syncback Imageson page 46.

Advanced Settings for Out-of-Band File SystemsTo configure advanced protection settings for out-of-band file systems:


2. ClickApp> Local> File Systems.

3. Select the protected file system from the navigation pane.

4. Click the blueAdvanced Sett ings link in the upper right corner. The Advanced Settings page appears:

5. Select Take application consistent backupfrom the Application Consistent drop-down list.

6. Provide the start paths in the Start Pathfield. Start-path specifies the point in the file system where

backup starts. If the start-path field is left blank, backup starts at the root directory of the file system to be

backed-up. For example, a value of / usr / l ocal will back up the / usr / l ocal directory whenprotecting applications on a Linux host. Click Add to define additional start paths.

7. Provide the prune paths in the Prune Path(s)field. Use Add link to add a path. Prune-path specifies a

point in the file system where directory traversal will stop. When protecting a Linux application, a value of

/usr/local/lib will ensure that nothing below / usr / l ocal / l i bis copied, but all other directories and filesin /usr/local are copied. If this field is left blank, every subdirectory of the start paths is backed up. Click

Add to define additional prune paths

8. Enter the file name patterns to be excluded from backup in the Exclude Pattern(s)field. You can

exclude certain file types from the backup. Using this option, only the most crucial data is backed-up

leaving aside the non-critical files. Guidelines for exclude patterns:

Using this option, only files are excluded, directories are not excluded.

A pattern can include wild-card characters, for example, an asterisk (*) or a question mark (?). To

exclude all the files that contains .sys as extension, enter *.sys in the Exclude Pattern(s) field.

On Windows, files named pagefile.sys and hiberfil.sys that appear in the root directory of a driveare automatically ignored.

9. Enter the staging disk size, in gigabytes, in the File system Staging Disk Size (GB)field. By default, the

Actifio Connector uses the size of the protected file system as the size of the staging disk. This setting

allows the administrator to override this value, for example to allow for growth of the file system.

10. Choose Do not Unmap if required. This maps temporary staging disks to the host to be used during

data movement. LUNs are mapped during the first job, all subsequent jobs reuse the mapped LUN.

11. Click Savetoupdate the changes.


23/56

19



Advanced Settings for Oracle Databases

Note: In order to protect an Oracle database, you must have database login details with sysdba privileges.

During the protection process, you must enter the credentials, enter the user name and password and then

click Protect to proceed. If the password contains any special characters, then it must be entered in double

quotes. Using @ in a password is not supported.

To configure advanced protection settings:


2. ClickApp> Local> Oracle.

3. Select the protected database from the navigation pane.


5. Enter the number of RMAN channels in the Number of Channels field. You can set the maximum

number of channels up to 8. The default value is 1.

6. Enter the staging disk size in the Staging Disk Size (GB) field. By default, the Actifio Connector

calculates the max size of the database as configured. The Staging Disk Size option allows you to

allocate a staging disk to hold backup and to allow future growth of the database.

For example: adding more table space, data files while the backup still maintains incremental behavior.

This staging disk is thin provisioned. Another use case of this staging disk size, after user restored the

whole database from PAS backup and when open the database with reset log; you must take a level '0'

backup again. In the current release this is not done automatically by the Actifio Connector. To force a

new level '0', you must change the staging disk size and then save. Next backup will perform a new level

'0'. The unit is in GB.

7. Enter the RMAN log path in the RMAN Log Locationfield. This is the custom location (full path along

with RMAN filename) where RMAN writes the logs while taking the backup.

For Linux, the default log location is / act / l og/ si d_r man. l og.If you change the path, the value must be in the form / act / l og/ t est / cust om_r man. l og


24/56


20


For Windows, the default log location is c: \ act _t mp\ l og\ si d_r man. l og.If you change the path, be sure there are no spaces in the path.

8. Choose to validate each backup before restoring it. RMAN provides restore validate for the backups,

when this option is provided (true), the Actifio Connector invokes RMAN restore validate command for

each backup.

9. Enter the Oracle catalog database name if one is used in the Catalog DBNamefield. This field is used

only when you are using a catalog database for RMAN repository. By default, a control file is used.

10. Enter the Oracle catalog database user name in the Catalog Userfield. This field is used only when you

are using a catalog database for RMAN repository. By default, a control file is used.

11. Enter the Oracle catalog database login password in the Catalog Passwordfield. This field is used only

when you are using a catalog database for RMAN repository. By default, a control file is used.

12. By default, Oracle backup skips inaccessible and offline tablespace/datafiles. If you do not want to skip

these, then select an option from RMAN Backup Not Skip drop-down field.

13. Enter the oracle database service name in Oracle Servicenamefield. This is optional for a standalone

instance but required for a RAC setup.

14. Enter the IP addresses of cluster nodes in the cluster nodesfield for fail-over choice in this format:1: 172. 16. 16. 21: svc_orarac2_act : F [ f ai l over r ank] : [ f ai l over nodei p] : [ ser vi cename on f ai l over node] : [ r ol e of member node] r ol e of member nodeby default should be F(failover).It can also be M(maintenance). When a cluster member role is specified as M, then PAS uses it as the

primary backup node instead of using the original RAC node. A maintenance node in RAC is normally

responsible for backup and other maintenance tasks of the RAC setup.

15. Choose Do not Unmap option if required. When this option is selected, temporary staging disks

mapped to the host and used during data movement remain mapped to the host. LUNs are mapped

during the first job and all the subsequent jobs reuse the mapped LUN. By default, this option is option is

selected.

16. Select whether you want to truncate the logs after every backup. When this option is selected, application

related logs are truncated till the recent or current backup.


Disabling OS Authentication for Oracle

Windows OS authentication allows Oracle to delegate control of user authentication for the database to the

operating system. Due to this, any test credentials for Oracle database accepts any invalid user name/

password and always shows the test result successful. To avoid this, you must disable the OS authentication

for Oracle.

To disable OS authentication for Oracle:

1. Log on to the Windows machine through which the Oracle Database was discovered.

2. Open Computer Management.

3. Under System Tools, expand Local Userand Groups.

4. Select Groupsunder Local User and Groups, select ora_dba on the right panel.

5. Click on More Actionsunder ora_dba on the second right panel.

6. Click on Properties.

7. SelectAdminist ratorunder Membersand click Remove.

8. ClickApplyand then OKto close dialog box.

Advanced Settings for CIFS ShareTo configure advanced protection settings for CIFS Share:


2. ClickApp> Local> CIFS.

3. Select the protected CIFS share from the navigation pane.


5. Provide the start path names in the Start Path field. Start-path specifies the point in the CIFS share

where backup starts. If the start-path field is left blank, backup starts at the root directory of the filesystem to be backed-up. For example, a value of \ \ SERVERNAME\ SHARENEAME\ abc will back up theabc directory on the CIFS Share when protecting applications on a Windows host. Click Add to define

additional start paths.

6. Provide the prune paths in the Prune Path(s)field. Prune-path specifies a point in the file system where

directory traversal will stop. When protecting a Windows application, a value of

\ \ SERVERNAME\ SHARENEAME\ abcwill ensure that nothing below\ \ SERVERNAME\ SHARENEAME\ abc is copied, but all other directories and files in \\

9. Enter the CIFS share password in File system Passwordfield.

10. Enter the staging disk size, in gigabytes, in the File system Staging Disk Size (GB)field. By default, the

Actifio Connector uses the size of the protected file system as the size of the staging disk. This setting

allows the administrator to override this value if necessary, for example to allow for growth f the file

system.

11. Choose Do not Unmap option if required. When this option is selected, temporary staging disks

mapped to the host and used during data movement for backup remain mapped to the host. LUNs are

mapped during the first job and all the subsequent jobs reuse the mapped LUN. By default, this option is

selected.

Mounting a Backup ImageMounting a backup image results in creating a virtual copy of the selected image and presenting it to the

selected host. This virtual copy is fully read/writable, but does not consume any additional storage at the time

of creation. Further changes to it will require incremental additional storage.

After mounting the image, you can either use it directly or restore individual files or directories from the

mounted image as described in Restoring Selected Files/Directorieson page 37.

Actifio PAS lets you mount one or more backup images from:

A VM to the same VM, to another VM, or to any other host. The mounted image is displayed as a new

drive on the mounted VM or host.

An Application to the same host, to another host, or to a VM.

Actifio PAS mounts images transparently to a host/virtual machine and does not require additional zoning (if

that was done originally) or shutdown/restart of the host/VM.

Multiple backup images can be mounted to the same host or VM. Any mounted image can be unmounted

individually.

Before mounting an image, ensure that the WWPN/iSCSI port of the host where the backup images will be

mounted is accessible to the PAS. This mount operation is applicable for all applications and VMs.

To mount a backup image to a host:

1. Open the Application Manager to the Restore tab.

2. Select the application or VM from the navigation pane.

3. Select the time period for backups using the calendar icons to filter the list of backups as needed.

4. Select the backup image type by clicking on the corresponding Snapshot, Dedup, Remote, or LiveClone

buttons. You can use the Shift key to select multiple types.

5. Select the backup image to mount from the list on the right. The selected image icon turns green and

detailed information about it is displayed in the image box at the center of the display.


35/56

6. Click the pull-down menu from the bottom right of the image information display and select Mount. The

Mount Job window is displayed:

Selecting a Physical Host (left) and a Virtual Machine (right) as Host

7. If required, change the default storage pool from the Select default storage pool drop-down list.

8. Select a host (physical or virtual) from Select Host(s) drop-down list.

If the backup image is of a physical host, skip to Step 9.If the backup image is of a VM, select a Hostto Mount:

Existing Hostoption: Select the host that you want to mount from the Choose from existing hosts

drop-down list. The selected host must be a SAN host or a Virtual Machine on ESX Server that is

connected to Actifio PAS. Select a single or multiple volumes to mount from Select volumes to mount. By

default, all the volumes are selected. If you mount to an existing VM, the VM disks will show up as a new

file system drive on the VM.

New VMoption: Enter a name for the new VM that you want to mount, specify a vCenter server, an ESX

host, and a datastore in Select vCenter Server, ESX Host, and Datastorerespectively. Actifio PAS

must write some configuration data to the selected datastore to point to the mounted volumes, but nostorage will be consumed by the backup image virtual copy.

Select a single or multiple volumes to mount. By default all the volumes are selected. The first volume

cannot be deselected.

Note:Acti fio Desktop assumes that the f irst volume of the VM is the boot volume. If the selected

first volume is not the boot volume, contact Actifio support for further assistance or refer to the

CLI Reference Guideto perform this task using the CLI.

If you select a virtual machine, select vRDM or pRDM as mount mode, by default vRDM mode is

selected. For file level restore operations, use the pRDM mode.

9. Select a single volume or multiple volumes from Select volumes to mount. By default, all the volumes are

selected. For an individual file system there may be only one volume, for VMs, consistency groups, and

generic applications there might be more volumes.

10. Click Submit . A job is submitted to mount the image to the selected host.

Note:A mounted image can be used directly from the mounted host or you can restore selected the files or

directories from it. See Restoring Selected Files/Directorieson page 37.

If the Actifio Connector is installed on the host on which you have mounted the image, then the backup image

is mounted to:

C: \ Wi ndows\ act \ J obname_j obi d on Windows or / mnt / act / J obname_j obi don Linux.

If the Actifio Connector is not installed, you need to manually mount the new disk that is visible on the host.

Note: The original backup image is never modified, even if the mounted virtual copy is modified or mounted

and deleted.


37/56

33



Cloning a Backup ImageYou can create two types of backup images: clones and LiveClones.

Clone Images

When Actifio PAS clones a backup image, it creates a full copy of the image that consumes as much storage

as the original application data. This is different from a Mount operation, which uses a virtual copy that does

not take additional storage.

Actifio PAS copies the contents of a VDisk to another VDisk that can be mapped to any SAN host. The cloning

operation is applicable for all the file systems and applications.

LiveClone Images

A LiveClone is an independent clone of a backup image that consumes full storage resources and can be

mounted to a host. It can be refreshed incrementally from another backup image, allowing very fast and

efficient data refreshes for ETL and test & development purposes. A LiveClone can also be mounted for direct

modification to support operations such as data masking.

LiveClones provide a crucial building block in managing copy data lifecycle as they combine the performance

and independence of a full clone with the efficiency and speed of incremental refreshes of data.

Cloning an Image

Restoring a Backup ImageRestoring replaces the original production application data with the backup image. This will result in the loss of

all current application data as the application will be restored to its status at the point-in-time when the backup

image was created. This operation cannot be undone.

Actifio PAS lets you restore a backup image from a VM host to the same VM host or from a non-VM host to the

same non-VM host.

Note: When you restore a backup image, the SLA options (Run Schedule, Expire Data) of the protected

application are turned off.

Note: For Oracle databases, protected out-of-band restore function is not supported. Use the Clone and Mount

methods instead.

To restore a backup image:


2. Select the application or VM to restore.


4. Select the backup image type by clicking on the corresponding Snapshot, Dedup, Remote or LiveClone


5. Select the backup image to restore from the list on the right. The selected image icon turns green and


6. From the pull-down menu, select Restore. The Restore Job window is displayed.

7. Select a single volume or multiple volumes to restore. By default all the volumes are selected.

8. Click Submit . A warning dialog appears. Read the warning message carefully and then Enter DATA

LOSSin the provided field to confirm.

9. Click Start Restore. The image is restored. For VMs, Actifio PAS removes the relevant VMDKs from the

VM being restored and creates new VMDKs populated with data copied from the backup image.

Note: The Restore operation cannot be performed from a remote cluster. However, you can use a remote-

dedup image for a restore operation on the source cluster itself.


41/56

Note:Actifio PAS maintains thin/thick provisioning of the original VMs while cloning/restoring a VM snapshot.

For VM snapshot images created prior to Actifio PAS 5.1.2, cloned and restored VMs will be thin provisioned.

Restoring Selected Files/Director iesYou can download a subset of files or directories from a backup image mounted to the host. This feature is

supported only on Windows-based file systems. The restoration includes zipping the files and downloading the

zipped file on the client running Actifio Desktop.

Prerequisites to perform this function:

The Actifio Connector is installed and running on the mounted host.

The Application Discovery function is executed at least once on the mounted host.

To restore selected files or directories:


2. Select the desired Application or VM from the navigation pane. If you are selecting a VM, ensure that the

Actifio Connector is installed on the Virtual Machine and applications on the VM are discovered.

3. Mount the image as detailed in Mounting a Backup Imageon page 30.

4. The Restore image is populated. The Active Images pane lists the images mounted on the host.

5. Select a mounted image from the list.

6. Click the image information action pull-down menu at the bottom right.

7. Click Restore File(s). A tree view of the directories and files of the image is displayed.

8. Select the files and/or directories to restore by double-clicking the folder or file. You can select the files in

a directory by opening the directory by clicking the arrow mark displayed against the folder. You can see

the selected files or folders under Items to Restore. You may use the delete option to de-select files or

folders.

9. Click Submit . The Save As window appears.

10. Select a destination folder on the client running Actifio Desktop.

11. Enter a name for the zip file.

12. Click Save. The Actifio Connector zips the selected files and directories and starts the download.

Note: To prevent unauthorized access to sensitive information, Actifio recommends you

download the required files to a secure local disk or a NAS mount then share the files with the

required operators.

Forcing the Expiry of a Backup ImageYou can force the expiry of a backup image earlier than its scheduled time in order to gain storage space.

Expiring deduped backup images may not free any storage if data blocks are shared with other backup images

of the same or different applications. In any case, no storage will actually become available until a full Dedup

Garbage Collection sweep is performed. Garbage Collection is managed under the Domain Manager Dedup

tab. It is detailed in Configur ing Ac tifio PAS 5.1 for Your Data Environment .

To force the expiry of an image:


2. Select the backup image type by clicking on the corresponding Snapshot, Dedup, Syncback, Remote, or

LiveClone button.You can use the "Shift" key to select multiple items.

3. Select the required image. The color of the box representing the image turns green on selection and the

image details are displayed on a tab.

4. Click the image information action pull-down menu at the bottom right.

5. Select Expire. The image is deleted.

Verifying a Deduplicated Backup Image

Note: Before verifying a backup image, configure a deduplication schedule.

You may want to verify whether a deduplicated backup image passes a data integrity check to ensure it can be

used in a live system.

To verify a deduplicated backup image:1. Open the Application Manager to the Restore tab.

2. Select the deduplicated images available by clicking Dedup.

3. Click the image to be verified. The box representing the image turns green on selection.

4. From the pull-down menu in the bottom right, click Verify. The verification job pop-up appears.

5. Click Submit . A warning message appears.

6. Click Yesin the confirmation dialog. You can view the current jobs in the System Monitor service to track

verification progress.

Note: You can schedule this process through the SLA Architect. See Planning and Developing Service

Level Agreementsfor details.

Protecting Applications with

Dedup- Async ReplicationDedup-Async Replication (DAR) is a very powerful tool.

This chapter includes:

About Dedup-Asynchronous Replicationon page 41

Configuring Dedup-Async Replicationon page 43

Restoring a Synchronized Imageon page 50

About Dedup-Asynchronous ReplicationDedup Async Replication (DAR) provides disaster recovery protection for applications and virtual machines by

moving protected data from local PAS to remote PAS and making it available for immediate access from the

remote site. Data movement is done over IP networks after global de-duplication and compression using

proprietary patent-pending technology, thereby significantly driving down bandwidth requirements and costs.

This allows wider protection of applications where traditional solutions are cost prohibitive.

Dedup-Async replication makes replication effortless by:

Using the existing IP network to replicate data.

Replicating repeatedly at intervals determined by policy so that network bandwidth is conserved while

meeting the configured Recovery Point Objective.

De-duplicating data before replicating so that bandwidth consumption is much lower than the change rate

of the application.

Creating a remote re-hydrated image that the application can instantly and transparently fail-over to.

Making disk management transparent. (Optionally) Replicating VMs to a datastore on the remote site.

Making it simple to fail-over the application to a host on the remote site.

Making the synchronization of data back from the remote PAS cluster to the local PAS cluster, simple and

non- interruptive to the application's I/O activities.

Cleaning up all remote images created after the application fails back to the local PAS cluster.

Note: For more information on DAR, seeActi fio PAS Dedup-Async Repl ication in the Actifio Documentation

Library.

Protecting ApplicationswithDedup AsyncReplication

States of a Protected ApplicationThe four states of an application protected using a dedup-async policy are:

Unprotected: An application is

unprotectedwhen no SLA is associated

with it.

Protection Initialization: An SLA is

associated with an application but the first

protection job is yet to complete.

Protected: An application becomes

protectedwhen the first replication job

completes successfully, or when the

application is failed back. This state

indicates that there is at least one

replicated image to fail over to.

An application remains inthis state as

long as the SLA associated with it is notremoved or the application is failed over.

When you remove the SLA, the

application becomes unprotected.

If the application fails over to a remote

site, its state changes to failed over.

Note that testing the failover capability

does not alter the state of the application.

Failed Over: In the failed overstate, the application, which is also configured on the remote site, accesses the

remote image directly. Consequently, replication to the remote site is paused. When the application is ready to

operate from the local site, you can synchronize the data back to the local site optionally. The Syncback process

can be carried out multiple times.

After synchronizing the data:

1. Shut down the application on the remote site

2. Perform one last Syncback operation to make sure all changes were captured

3. Restore the local application form the syncback image

4. Fail-back the application to the local site.

The application state changes to the protected state and the replication to the remote site is resumed. If you

remove the SLA, the application state changes to the unprotected state.

Authent ication and Data Encryption

The authentication process between PAS clusters is performed using the 1024-bit certificates, and thereplicated data is encrypted using the AES-256 encryption standard.


47/56

Configuring Dedup-Async ReplicationDedup-Async Replication (DAR) enables you to create a highly available image of an application's data over

an IP network and to protect numerous applications with relatively little bandwidth. DAR creates a deduped

backup image on a remote cluster. This image is replaced by a new image as the policy is set off periodically

based on the configured frequency. As a result, there is always only one image of 'dedup async replicated' type

on the remote cluster. This image can be readily used to execute a failover or a failover test. Later you can fail

back the application to the local cluster.

To configure dedup-async replication of data from a local cluster to a remote cluster, you need:

A local cluster joined with a remote cluster in the sharing or non-sharing mode.

A policy for dedup-async replication is configured as described in Planning and Developing Service

Level Agreementsin the Actifio Documentation Library.

A resource profile configured to include the remote cluster as described in Creating a Resource Profile.

An SLA defined as described in Protecting an Application.

When all the above are configured, dedup-async replication of data is started as per the schedule defined in

the policy template resulting in the creation of an image of the application data on the remote cluster.

When multiple deduplication policies are defined for an application, only one of the local, remote, or DAR jobs

runs at a time. The other policy schedules are queued and are run subsequently based on priority.Dedup-async replication entails:

Selecting the Storage PoolYou can select a storage pool to create the backup image as part of dedup-async replication. Each cluster can

configure a separate storage pool that will be used for applications replicated from each of its joined peers.

1. Log into the Actifio Desktop on the remotecluster.

2. Open the Domain Manager.

3. Select System> Configuration> Cluster Settings> Cluster Managerfrom the navigation pane. A listof joined clusters is displayed.

4. Click the Storagetab for the local(source) cluster that you want to configure.

5. Select the storage pool from Destination performance pool. These are the storage pools defined on

the remote PAS cluster. When you select a pool, the DAR images for applications from the local (source)

PAS cluster are stored here.

6. Click SaveSettingsbutton to update the changes.


49/56

45


ProtectingApplicationswithDedup AsyncReplication

Testing FailoverAfter configuring dedup-async replication, you may want to test the failover of an application to determine the

readiness of the remote cluster in the event of a mishap. When you test failover, a virtual copy of the most

recently replicated image of the application is created and presented to the host that you select. You can log on

to the host and verify that the replicated image is consistent. After you have tested the image, delete the test

failover image to free up any resources it occupies.

To test the failover operation, specify a host to which you will mount the failover image. Note that you cannot

failover a virtual machine application to the same virtual machine.You can test failover from the remote PAS

cluster. When you test failover, a failover job is started. When the job completes with the job status 'successful',

the test-failover operation is successful. You can mount, log on to the host, and view the failover image to

ensure the consistency of data and your complete DR procedure.

You can have only one image test-failed-over to one host at one time. For example, when a failover image is

available on the remote PAS cluster and the PAS cluster is managing two hosts, A and B, you can host the

image on either A or B but not both. When the image is already mounted on the host A, you can unmount the

image from A and then mount it on B.

Before performing a test failover, ensure that the WWPN/iSCSI port of the target host where the backup image

is to be mounted is accessible to the remote PAS cluster.

To test failover, access the remote PAS cluster using Actifio Desktop and:

1. Open the Application Manager to the Restoretab.

2. Select the application from the navigation pane, from the Remote list. The last successful backup job is

displayed.

3. From the image information action pull-down menu, click Test Failover.4. Select the target host to fail over the image.

5. Click Submit . The latest DAR image of the application is used to create a virtual copy and presents it to

the host you have selected. Since it is a virtual copy of the image, the host can use it without affecting the

actual DAR image. Later you can delete the image as described in Deleting a Test-Failover Image

section.


50/56


46


Deleting a Test-Failover ImageTo delete a test-failover image from the remote PAS cluster:

1. Open the Application Manager to the Restoretab.

2. Select the application from the navigation pane, from the Remote list.

3. Select the test-failover image from the Active Images pane at the bottom.

4. From the image information action pull-down menu, click Delete.

Deleting Failover, Test-Failover, and Syncback Images

Normally, all failover, test-failover, and Syncback images of an application are deleted when the fail-back

operation is executed. In rare cases, some images created as part of dedup-async replication of an application

may not be deleted.

To delete the failover, test-failover, and Syncback images of an application from the local and remote PAS

clusters:



3. Right-click the application.

4. Select the Cleanup Dedup Async option.

Note: If any of the images remain, the Cleanup dedup async option appears on right-clicking the

application. Use this option to delete the images. Alternatively, use the CLI cl eanup dedupasync - al l command to delete all images of the application.


51/56

47



Failing Over an Appl icationYou can failover the applications protected with a DAR policy from the local PAS cluster to a host connected to

the remote PAS cluster. Note that you should initiate the failover from the remote PAS cluster and you can

failover a VM only to a new VM.

When you start the failover task, dedup-async replication of the application data to the remote cluster is

stopped. If a dedup-async replication job is in progress, it is stopped when the application fails over. Snapshot,

local deduplication, and remote deduplication policies for the application, if any, continue to run on the local

cluster.

Before performing a failover task, ensure that the WWPN/iSCSI port of the host where the backup image is to

be mounted is accessible to the remote PAS cluster.

To failover an application:

1. Click Desktop> New Desktopto connect to the remote PAS cluster by launching another session of

Actifio Desktop.

2. Open theAppl ication Manageron the remote PAS cluster.

3. Select the shadow application from Remote in the navigation pane:

4. Click Dedup Async. By default, the latest image is selected for failover.

5. From the service menu, select Failover. The Failover Job window is displayed.

6. Select a host and the diskpool to failover to. When failing over a virtual machine to a new VM, enter the

VM's name, and select the appropriate values from the vCenter Name, ESX host, Datastore, and

Diskpool drop-down boxes.

7. Click Submit . A warning message is displayed.

8. Enter 'FAILOVER' in the text box.

9. Click Start Failover. A failover job is initiated. This job stops any dedup-async replication job in progress

for this application, and presents the latest replicated image to the selected host. You can now log on to

the host, bring up the application, and direct all the external clients to use this copy of the application.

When you are ready to bring back the data generated at the remote site to the local site, start the

Syncback operation.


52/56


48


Synchronizing Application Data Before Failing BackAfter an application from the local PAS cluster fails over to a remote PAS cluster, you can failback the

application to the local PAS cluster. Prior to failing back, you might want to bring back the latest data generated

at the remote site to the local site. There is no limit to the number of times synchronization is carried out. Each

synchronization results in creating a new Syncback image on the local PAS cluster.

The Syncback task should be executed on the remote cluster.



3. Click Syncback.

4. Click Submit.

You may want to repeat this task before failing back an application since the data on the remote PAS

cluster may change even as the data is being brought back to the local PAS cluster. Perform a Syncback

one last time after you shut down your application on the remote site and before failing back to avoid any

loss of changes.

Though the newly generated data from the remote application is brought back to the local PAS cluster, it

is not automatically applied to the original image of the application. Instead, it is made available on the

local PAS cluster as a Syncback image.

Note: Before you failback, make sure you Restore your local application using the latest

Syncback image.

You can view the synchronized image on the local cluster at Application Manager > Restore > Syncback.

A synchronized image is yellow. You can mount, clone, or restore a synchronized image.


53/56

49



Failing Back to the Local PAS ClusterYou can fail-back an application to a cluster on which the application was originally running before the

application failed over to the remote PAS cluster. You should execute this task on the local cluster.

Before failing back an application, it is recommended that the synchronization task is carried out at least once,

as described in Synchronizing Application Data Before Failing Backon page 48and that the Syncback image

is used to restore the application as described in Restoring a Synchronized Imageon page 50.

However, you can fail-back without synchronization. Synchronization creates a Syncback image on the local

PAS cluster. You can mount, restore, or clone the Syncback image as described in Cloning a Backup Imageon

page 33. Synchronization should be followed by executing the fail-back.

Fail-back deletes the Syncback images brought back from the remote PAS cluster and the failover image that

may still be mounted on the remote PAS cluster. Fail-back also deletes the test failover images that might be

around on the remote PAS cluster. After these steps are complete, it marks the application as being in the

protected state, and resumes DAR of the application data from the local cluster to the remote cluster.

When you restore a Syncback image, the original image on the host that failed over is replaced with the

Syncback image. However, you can mount or clone a Syncback image to any host configured using Actifio

Desktop.

To fail-back an application from the remote cluster to the local cluster:1. Log into the Actifio Desktop on the localcluster and open the Application Manager.

2. Select the failed over application from the navigation pane.

3. Click Failback . A warning dialog appears.

4. Type FAILBACK in the provided field. On successful fail-back, DAR to the remote cluster is resumed.


54/56


50


Restoring a Synchronized ImageAfter synchronizing back an application's data, you typically need to restore the application data from the

synchronized image. The restoration replaces the application's image in use prior to failover with the latest

image that includes changes from the remote site.


2. Select the application from the navigation pane.3. When restoring a non-VM application, shutdown the application and unmount the file system. When

restoring a VM application, power off the virtual machine.

4. Select the latest Syncback image. It is yellow in color.

5. From the image information action pull-down menu, select Restore. A warning message appears.

6. Enter DATA LOSS.

7. Click Start Restore. A restore job is started immediately.

8. You can verify that the restore operation is successful by viewing the job status in System Monitor.

9. After the restore operation is completed successfully, for a non-VM application, mount the file system,

and restart the application. When restoring a VM application, power on the virtual machine.
