What is VCB ?

Why VCB ?

VCBTSM 5.5 Integration

How does VCB work with TSM?

Whats new in TSM 6.1

Customer Value


3/26




What is VCB ?

VMware Consolidated Backup (VCB) interface from VMware

Official backup interface to backup VMware machines online

Enables backup vendors like TSM to perform VMware backups

Not a Backup product by itself !

Enables centralized off-loaded backups on a dedicated backup proxy server

Allows for consolidated backups of multiple VMware machines

Supports SAN environments

Part of VMware Infrastructure Enterprise Edition and can be purchased as

add-on product to VMware Starter and Standard Editions


4/26




How does VCB work?

VCB quiesces all virtual machines on ESX Servers and opens

their files up to access by a backup proxy server. It does it by

creating VMware snapshots. This allows TSM to either backup

the data as full VMware machines images or as individual files.

While the VMware machines are in this state all of the following

changes are written to a delta file. After the backups have

finished the delta file will be applied and VCB deletes the former

snapshot.


5/26




Why VCB ?

Traditional methods of backing up VMware have disadvantages:

No officially supported VMware Backup interface before VCB

Backup load on ESX Server impacts ESX Server significantly since it is cumulative

5% CPU load is OK until you have 20 virtual machines backing up at once

Backup load is very difficult to virtualize

Intense Disk I/O coupled with intense Network I/O

Backing up disk images over the VMware Service Console is slow

Consistency issues with online backups of .vmdk files

Manual scripting required for SAN, proxy-based, consolidated, backups

Availability impact on large VMware environments

-> VCB helps to cope with large VMware production environments


6/26




Benefits of VCB-TSM Integration

Integrated supported product-based solution to protecting VMware with TSM

Fast online (hot) backup into TSM

Near Zero Impact Backup on ESX Servers by using proxy backup server

Coordinated backup of multiple virtual machines into TSM

Management of virtual machine backup data in TSM

Live user-transparent file-level restore from within running virtual machine

Disaster Recovery from TSM via Full-VM restore*

*Not to confuse with TSM B/A Client Image level backup which works on volume basis and is not used

Two VCB Backup Methods

1. VCB File-level backup

2. VCB Full-VM backup*

*Not to confuse with TSM B/A Client Image level backup wich works on volume basis and is not used

VCB File-level Backup

VCB takes snapshots of virtual machine drives

VCB mounts the virtual machine snapshot over the SAN to a directory on the backup proxy

Works for files inside the virtual machine on individual file/directory level

Can use incremental forever file backups and individual files can be restored

No physical data movement to the backup proxy

Currently only supported for Windows virtual machine OSs

Protects against data loss inside the virtual machine Backup is off-loaded from ESX Server

Parallel backup into TSM

TSM Windows B/A Client installed backup proxy

VMware currently supports Windows 2003 (32 and 64 bit) as backup proxy OS

Each VMs data is automatically stored under their specific TSM Nodename

No specific VCB File-Level restore, 2 options for recovery:

1. Option: Install TSM B/A Client inside virtual machine and restore files from there

2. Option: Restore data to backup proxy and move it to original location

VCB Full-VM Backup VCB provides set of files which represent full images of virtual machines

Image level virtual machine backups are OS neutral

Windows, Linux, all other virtual machine OSs (guests) are supported VCB exports the virtual machine snapshot to a directory on backup proxy Physical data copy takes place to make it available on backup proxy

Includes virtual machine disk images ( .vmdk files) and configuration files

Protects against data loss of the complete virtual machine (Disaster Recovery)

Backup is off-loaded from ESX Server

Parallel backup into TSM

Works only full (not incremental), but TSM Subfile level backup can be leveraged

TSM Windows B/A Client is installed on backup proxy

VMware currently supports only Windows 2003 as backup proxy OS

All data are stored under the proxy server TSM Nodename

VCB Full-VM restore:

Last backup might still be on local disk and can be restored

Data (.vmdk files) can be restored from TSM Server into the SAN

Optional: VMConverter utility extracts individual files from .vmdk files


12/26




New in TSM 6.1

Full VM backup/restore integrated in TSM

Command Line: TSM Full VM backup

GUI: Action -> Restore

VMware Backup/Restore integrated in TSM Client GUI

Exports are broken into 2 GB file chunks

TSM Client backs up chunks at a file level

Size is tunable (2 GB is default for subfile level backup)

Enhanced password management

ESX Server 3.i has no service console

TSM Linux client based backups are no option anymore

File Level recovery

From a VCB File-Level backup: Restore individual files from within the guests

From a VCB Full-VM backup:

Restore the complete VM and use VMware ExtractUtility for individual files.

TSM Command Line/GUI integration of the VMware

Extract utility planned for the future


19/26




Applications and Databases inside VMware

How are Applications and Databases running inside virtual machines

being backed up?

Even with VCB, applications and databases are not consistently being

backed up since transactions could be in transit (from memory) and

not consistently written to VMFS when the snapshot takes place !

2 Options:

1.Option: Quiesce database/application via VCB pre-scheduling before snapshot

(requires manual scripting, not recommended)2.Option: Use TSM for products (TDPs) in addition to VCB from within virtual

machines (recommended). Needs to be licensed in addition.

TSMs VMware Support History

TSM 5.3and up (Traditional VMware backups without VCB)

Run a TSM B/A Client from within the individual machines itself Run TSM B/A Client on Linux on the ESX Server and backup flat VMware files

TSM 5.4

Basic integration using the VCB integration module (TSMIM)

Recovery view of the data is centered around the VCB host

Manual Scripting involved

TSM 5.5

Integrated VCB product-based solution requiring no manual scripting for file-level backup

Does not require integration module from VMware

Better recovery and transparent management of the data on the TSM Server

User is removed from the fact that the backup was performed from a VCB backup host

Manage a virtual machine's backup data as if it had been backed-up by a TSM client runninginside the virtual machine

TSM 6.1

TSM GUI integration

TSM Command Line integration for Full-VM backups


21/26
