INTRODUCING QUESTNETVAULT BACKUP

Quest NetVault Backup – At a GlanceKey BenefitsFeature SummaryAbout this DocumentTarget AudienceRecommended Additional ReadingAbout Quest Software

Contacting Quest SoftwareQuest Support

1.1.0 Quest NetVault Backup – At a GlanceQuest NetVault Backup (NetVault Backup or NVBU) offers the most advanced, cross-platform data protection capabilities along with unsurpassed ease of use, out-of-the-box deployment and pain-free scalability. NetVault Backup allows you to safeguard your data and applications in both physical and virtual environments from one intuitive console. With the NetVault Backup Plug-ins, you are not required to understand storage, database or email internals. You select the backup strategy that best fits your database or email environment, and then just point and click. This enterprise-level software does not require you to be an expert, but has the flexibility to tune it as you want.

NVBU is engineered to keep up with the organizational changes and let you make choices that are best for your company. For example, if an organizational merger takes place or a key department acquires a major application that requires a different platform, that is no problem with NVBU’s heterogeneous server and extensive application support. The freedom of choice continues with the powerful disk-based data protection product, Quest NetVault SmartDisk (NetVault SmartDisk or NVSD) and its deduplication option which provides seamless integration with NVBU to allow you to be in control of which data should be deduplicated and which should not without restricting you to specific types of storage drives and appliances. Additionally, administrators have increased choice including the ability to copy or move data between NVSD Instances, to Virtual Tape Library (VTL) or tape-based devices in order to place redundant backups at offsite locations for failover and disaster recovery purposes. You can select your

Chapter 1Introducing Quest NetVault Backup

backup device of choice from a very large list of supported Network Attached Storage (NAS), VTL and tape systems. You decide when and where to encrypt to reduce backup windows while still meeting regulatory requirements. You can deploy and protect physical or virtual machines. With the NVBU Plug-ins, you easily select the best backup method to protect all the popular operating systems, messaging and database applications. NVBU SmartClient gives you the freedom to attach virtual and physical tape devices where you want to.

NVBU is architected to protect and leverage existing investments in data protection while making necessary changes and upgrades to support the growth and health of your organization. NVBU’s ability to efficiently scale from small installations to very large global companies means you would not be penalized by being forced to rip and replace your data protection infrastructure just because your organization is successful and growing. NetVault SmartDisk integrates with NVBU to shrink backup windows and reduce storage costs with its post-process deduplication option which can be scheduled outside the backup window. Your investment in storage systems is protected through automated access to hundreds of different storage devices. You avoid vendor lock-in by taking advantage of NVBU’s heterogeneous server support as well as powerful messaging, database and virtualization protection options. With NVBU, you protect your vital IT assets because you can still recover your data even in a worst case scenario in which you only have your backup media, but no NVBU database. Plus, you can redeploy into a different operating system for an emergency recovery.

NVSD uses patented byte-level, variable block data analysis technology to reduce data storage footprints by up to 90%.Virtualization Support – Extend advanced data protection to VMware and Hyper-V environments. A NetVault Backup plug-in gives you consistent, reliable, point-and-click backup and restore for virtual environments without requiring you to be an expert.Application Protection – Ensure availability of business-critical applications such as Oracle, SQL Server, Exchange, SharePoint, MySQL, PostgreSQL, Domino, Informix and Sybase with application plug-ins. These plug-ins complement native solutions to save you time on integration – no scripting is required to run backup and recovery jobs.Network Attached Storage Protection – Safeguard NAS data directly on a locally attached SCSI device, a SAN-attached device (tape or VTL) or a storage device elsewhere on the network.Enterprise-Wide Control – Give backup administrators the flexibility to define, manage and monitor jobs from remote locations of their choice. NetVault Backup’s automated features for global event notification and policy-based job management simplify their tasks across heterogeneous storage networks.Strong Security – Meet regulatory requirements without sacrificing backup windows or deduplication performance with an encryption plug-in for CAST-128, AES-256 or CAST-256 algorithm support. Flexible job-level encryption lets you easily select which data to encrypt.Flexible Storage Attachment – Attach storage wherever you like with the built-in NetVault Backup SmartClient. It allows you to easily distribute both real and virtual backup target workloads throughout the backup domain.Dynamically Shared Device – Share stand-alone and library-based tape drives among backup servers and SmartClients in SAN or shared-SCSI environments. This allows you to optimize workloads and maximize your equipment investments.

Auditor Daemon – An OverviewGenerating Audit Logs for Failed User RequestsCreating a User-Defined Policy for Deleting Audit LogsCreating a User-Defined Schedule for Purging Audit LogsDisabling Automatic Purging of Audit LogsConfiguring Concurrent Sysop Operator Messages

4.1.0 Auditor Daemon – An OverviewThe Auditor Daemon (nvavp) runs on the NVBU Server. This process tracks and controls user activities. It validates each user request, and depending on the user privileges, grants or denies the request. The Auditor records these events in the audit log, which is also known as the Audit Trail. The audit log is named audit.bin and resides in the ...\db directory (where ... represents the NVBU installation directory). You can view these logs using the NVBU Audit Trail report. For details on the Audit Trail report, refer to the Quest NetVault Backup Administrator’s Guide.

By default, the Auditor logs each user activity regardless of whether the request is granted or denied. It automatically deletes the logs that are older than 31 days. You can customize the Auditor to log only failed user requests, or create a user-defined policy for deleting audit logs. The default behavior and properties of the Auditor can be changed from the Auditing tab on the Configurator.

4.2.0 Generating Audit Logs for Failed User RequestsBy default, the Auditor logs each user request, regardless of whether the request is granted or denied. To override this behavior and generate audit logs only for the failed user requests, use the following steps:

1. Click the Auditing tab on the Configurator.2. Configure the following parameter:

4.6.0 Configuring Concurrent Sysop Operator MessagesIf you set up the Sysop Operator Message notification method for several events and these events are raised repeatedly in NVBU, the process manager may eventually run out of available resources and hang. To prevent this, NVBU limits the number of simultaneous notifications that are started on a system. If any new notification causes the count of active notifications to exceed the configured limit, NVBU will discard it with the following Operator Message in the NVBU Status window:

Too many simultaneous notifications. Refusing further notifications

The Auditor Daemon will not relay any other notification until the count of active notifications falls below the defined limit. By default, this count is set at 5.

To change the count of active notifications

5.1.0 Device Scan Process – An OverviewThe Device Scan process (nvdevicescan) runs on the NVBU Server and SmartClients. This process enables automatic configuration of backup devices. It scans for locally-attached libraries and standalone drives on an NVBU machine. It can recognize devices manufactured by several vendors, although not all. The devices found can be added using the Automatic Device Configuration wizard. The Device Scan process is initiated during the following events:

NVBU Startup – Device Scan is configured to start automatically when you start the NVBU Service on a machine. It scans the hardware for new devices on the SCSI bus or attached to NDMP Filers. Since scanning for new physical devices can take a while to complete, you can disable device scan during NVBU startup or restrict the type of device it scans for.Post-Startup – Device Scan is also initiated when you open the NVBU Device Management window. It scans for new devices which are currently not added to the NVBU Server. You can disable this feature if no new hardware has been added, or configure the type of device it scans for.

The settings for Device Scan can be changed from the Device Scan and GUI –> Devices tabs on the Configurator.

7.1.0 Log Daemon – An OverviewThe Log Daemon (nvlogdaemon) runs on the NVBU Server and performs the following functions:

Records System Logs – The Log Daemon manages the system logs generated by various NVBU processes and writes them to log files. System logs are useful in tracking activities and troubleshooting problems. The system logs reside in the ...\Logs directory on the NVBU Server (where ... represents the NVBU installation directory). This directory can be relocated using Configurator. For details, refer to Relocating Logs and NVDB Directories on page 91. The log files are stored in binary format and named log-0, log-1, log-2, etc. The Log Daemon always reserves space for logs by creating a blank file. For example, when log-0 becomes full, it creates log-2 before opening log-1 for recording events. Log-0 and log-1 are created during NVBU installation. To make sure that the system logs do not continue to accumulate and consume disk space, the Log Daemon automatically deletes them after 30 days. You can change this behavior with a user-defined policy, or delete the system logs manually.

Chapter 7Customizing the Log Daemon

36

Performs Periodic Disk Space Checks – The Log Daemon performs periodic disk space checks, and issue alerts when the space usage reaches the defined warning or critical threshold. The disk space check applies to the following NVBU directories:

HomeDatabaseLogsReports

By default, the disk space check is scheduled to run every hour. You can reschedule or disable this event using the Configurator.

The default behavior and properties of the Log Daemon can be changed from the Logging Daemon tab on the Configurator.

7.2.0 Configuring Disk Space Alert ThresholdsNVBU defines two alert thresholds for disk space usage levels – Warning and Critical. These thresholds are defined as Percent Full of Total Disk Space, and set at 85 and 95 percent, respectively.

To change the warning or critical disk space threshold values

8.1.0 Media Manager – An OverviewThe Media Manager (nvmedmgr) runs on the NVBU Server and performs the following functions:

It manages the media database. The media database contains information about the media contents and online backup savesets.The Media Manager stores the device configuration details. It manages the backup devices through the Device Manager processes. The Media Manager issues high-level instructions for loading and unloading media, which are carried out by the Device Manager processes.It controls the selection of device and media for a job based on the media requests submitted by the Job Manager process.

You can change the default settings for the Media Manager from the Media Manager tab on the Configurator.

Chapter 8Customizing the Media Manager Process

44

Note: The NVBU Service must be restarted to apply any changes to the Media Manager Settings.

8.2.0 Configuring Retention Period for Imported BackupsNVBU cannot process data on media for which no information is available in the Media database. Such media are tagged as foreign media. Typically, media that are removed from the NVBU Server or swapped between libraries in different NVBU Domains are marked as foreign media. To access the savesets on foreign media, you must scan the backups and the on-tape indexes to import the required data from the foreign media to NVDB. For details on scanning foreign media, refer to Quest NetVault Backup Administrator’s Guide. The retention period for the imported data is determined by the backup life set for the savesets. For the savesets that have already retired, the data is temporarily stored for 7 days.

To change retention period for imported savesets

1. Click the Media Manager tab on the Configurator.2. Configure the following parameter:

Figure 8-1:Media

Manager tab

Minimum Life for Imported Backups – Enter or select the number of days NVBU should retain the imported data for a retired saveset. The default value for this parameter is 7 days.



45

8.3.0 Using Barcodes as Default Media LabelsWhile performing a backup, you can automatically label blank media using the Automatically Label Blank Media option available on the Target tab of the NVBU Backup window. When you select this option, NVBU concatenates the NVBU Server name, system name and a seed number to generate a unique label for each media item. You can also configure NVBU to use the media barcodes as labels for blank media instead of using a system-generated string.

To use barcodes as the labels for blank media


Use Barcodes as Labels – To use media barcodes as the default label for blank media during backups, select the Use Barcodes as Labels check box.


8.4.0 Setting Priority Levels for Continuation Media RequestsA continuation request occurs when an active backup or restore job requires additional media for completion. NVBU assigns a priority level of 5 to such requests so that they are not preempted by other media requests, and the active job completes without any interruption.

To change the default priority levels for continuation requests

1. Click the Media Manager tab on the Configurator.2. Configure the following parameters:

Continuation Restore Request Priority Boost – Enter or select a priority level for continuation requests by restore jobs. By default, these requests are assigned a priority level of 5.Continuation Backup Request Priority Boost – Enter or select a priority level for continuation requests by backup jobs. By default, these requests are assigned a priority level of 5.

Note that the priority level ranges from 1 (highest priority) to 100 (lowest priority). A priority level of zero sets a request to run as a background task



46

8.5.0 Setting Priority Levels for Media Labeling and Blanking RequestsNVBU assigns a priority level of 10 to media labeling and blanking requests. To change these settings, perform the following steps:


Label Request Priority – Enter or select a priority level for bulk media labeling requests. By default, these requests are assigned a priority level of 10.Blank Request Priority – Enter or select a priority level for bulk media blanking requests. By default, these requests are assigned a priority level of 10.

Note that the priority level ranges from 1 (highest priority) to 100 (lowest priority). A priority level of zero sets a request to run as a background task.


8.6.0 Configuring Callback Timeouts for Bulk Media OperationsThe callback timeouts for bulk media labeling and blanking operations control how long NVBU waits for user inputs before ending these requests. By default, NVBU waits for 120 seconds for user confirmation. The requests are not carried out if the callback timeouts expire for the operations. To change the default timeout settings, perform the following steps:


Bulk Label Callback Timeout – Enter or select a callback timeout for bulk media labeling request. The timeout value is specified in number of seconds. The default value for this parameter is 120 seconds.Bulk Blank Callback Timeout – Enter or select a callback timeout for bulk media blanking request. The timeout value is specified in number of seconds. The default value for this parameter is 120 seconds.



47

8.7.0 Setting Interval for Media Status UpdatesThe online media status is updated every 10 minutes on the NVBU Media Management window. To change this interval, perform the following steps:


Minimum Interval between Reporting Online Capacity – Enter or select the frequency of status updates for online media. The update interval is specified in minutes. The default interval is 10 minutes.


8.8.0 Disabling Reuse of Read-Only MediaNVBU automatically removes the read-only tag for a media item when the last saveset stored on is retired. This allows you to re-use the media for new backups. To disable this feature, perform the following steps:


Mark Expired Read Only Media as Writable – Clear this check box to prevent reuse of a retired read-only media. This check box is selected by default.


8.9.0 Creating a User-defined Policy for Automatic Index CompressionOnline indexes are the backup indexes stored in the NVDB. You can compress these indexes to reduce space usage. The backup indexes can be compressed manually from the NVBU Restore window, or automatically using an index compression policy. NVBU uses a default compression policy to automatically compress online indexes after 30 days of inactivity. To replace the default policy with a user-defined automatic index compression policy, perform the following steps:



48

Figure 8-2:

Indexcompression

parameters onMedia

Manager tab

Days of Inactivity before an Index is Compressed – Enter or select the inactivity period for index compression. The default value for this parameter is 30 days.


8.10.0 Creating a User-defined Schedule for Index CompressionThe Media Manager scans the NVDB at periodic intervals to find backup indexes which can be compressed. The scanning occurs every 12 hours. To change this schedule, perform the following steps:


Hours between Scans for Indexes to be Compressed – Enter or select the frequency of scans for index compression. The default interval between two scans is 12 hours.


8.11.0 Disabling Automatic Index CompressionTo disable automatic compression of online indexes, perform the following steps:


Days of Inactivity before an Index is Compressed – Enter or select 0 (zero).



49

8.12.0 Configuring Minimum Disk Space for Index DecompressionNVBU automatically decompresses the backup indexes when you try to browse or restore a saveset with compressed indexes. You can also manually decompress the indexes from the NVBU Restore window. For details on decompressing a backup index, refer to the Quest NetVault Backup Administrator’s Guide. By default, NVBU reserves 500MB of free disk space on the NVDB drive or partition, which is required before and after an index compression. To change this setting, perform the following steps:


Minimum Space for Index Decompression – Enter or select the minimum amount of space required on the NVDB drive or partition. The space requirement is specified in MB. The default value for this parameter is 500MB. A decompression request will fail in the following circumstances:

The available space on the NVDB drive or partition is less than the minimum required space.The required amount of free disk space will not be available on the NVDB drive or partition after a decompression. When NVBU receives a decompression request, it reads the index header to determine its decompressed file size. The request will fail if the available space on the NVDB drive or partition will go below the minimum required space after decompression.

If it fails, then NVBU will display an error message in one of the following windows:

When you issue the decompress command manually, NVBU will display the message on the NVBU Restore window.When NVBU performs an automatic decompression for a restore or an incremental backup, it will display the message in the NVBU Logs window.



50

8.13.0 Customizing the Diagnose Media Requests WindowNVBU supports a maximum of 64,000 characters on the Diagnose Media Requests for Job window. To reduce the number for characters displayed on this window, perform the following steps:


Maximum Characters in a Media Request Diagnosis – Enter or select the number of characters that can be displayed on the Diagnose Media Requests for Job window. It is specified in thousands of characters. Lesser number of characters may result in quicker output. However, the output may be truncated and you may not get the complete information. Therefore, it is recommended that you do not change the default settings for this parameter.


8.14.0 Customizing Device Related SettingsTo customize the device related settings controlled by the Media Manager, perform the following steps:

Do not Display Device Activity in the Device Window – Select this check box to stop status updates on the NVBU Device Management window. It may help reduce the load on the NVBU Server when several backup devices are added to the Server.Do Not Display Drives that are Available but not Active – Select this check box to hide the offline devices on the NVBU Device Management window.Only Check Available Drives and Media when Processing a Media Request – Select this check box to only check for available drives and media when a media request is received. It can be useful in large environment to reduce the network traffic generated by the automatic checks. However, it may cause a delay in job startup when several jobs are launched at the same time.Only Check Available Drives when Processing a Media Request – Select this check box to only check for available drives when a media request is received.Only Check Available Media when Processing a Media Request – Select this check box to only check for available media when a media request is received.Do Not Issue Prevent/Allow Media Remove Commands to Drives – During backup and restore operations, the Media Manager issues PREVENT ALLOW MEDIUM REMOVAL SCSI commands in order to move a medium to or from a drive. If your library software can handle medium removal/ejection by itself and does not require any explicit commands to be sent to the drive, then you can select the Do Not Issue Prevent/Allow Media Remove Commands to Drives check box. When this check box is selected, the Media Manager will skip the PREVENT ALLOW MEDIUM REMOVAL SCSI commands during device operations.Do Not Open a Device if the Serial Number has Changed – Select this check box to stop issuing commands to a device whose serial number has changed since its last configuration for NVBU.Unavailable Device Retry Interval – Enter or select the retry interval for unavailable devices. The retry interval is specified in minutes. By default, NVBU makes an attempt every 30 minutes to locate an unavailable device.Allow Library Modification when Jobs are Running – Select this check box to allow a user to modify the library settings while it is in use.Do Not Scan Unknown Media – When you add tapes to a library, and close the door (or restart the library), NVBU takes an inventory by reading the media barcodes. If NVBU cannot find the barcode for a piece of media, then it marks that tape as UNKNOWN. You can configure the Mark Unknown Media Blank parameter on the Configure Device


52

window to mark such media items as BLANK. For details on this option, refer to the Quest NetVault Backup Administrator’s Guide.If you do not mark the unknown tapes as BLANK, then NVBU starts loading each unknown tape into one of the drives to scan for backups and on-tape indices. On very large systems, this can increase the burden on the drive resources.To leave the unknown tapes as UNKNOWN and not scan them automatically, select the Do Not Scan Unknown Media check box. This option applies to all new libraries that are added to the NVBU Server. However, it does not change the setting for existing libraries. To apply this parameter to an existing library, you must remove the library and re-add it.You can also configure this parameter on a per-library basis. For details, refer to the Quest NetVault Backup Administrator’s Guide.
