Five things backup administrators should know about VMware Consolidated Backup

3:44 PM 1 Comments
How VMware Consolidated Backup Works

 Consolidated Backup consists of a set of utilities and scripts that work in conjunction with a third-party backup software. To ensure that Consolidated Backup works with the specific backup software, either VMware or your backup software vendor provide integration modules containing any required pre-backup and post-backup scripts.
The third-party software, integration module, and Consolidated Backup run on the VCB proxy, a physical or virtual machine that has Microsoft Windows operating system installed.
For specific versions of Microsoft Windows, see Configuring Windows on the VCB Proxy.
VMware Consolidated Backup Usage Models
To store and manage virtual disk files, ESX Server uses a variety of physical storage devices, including local disks, NAS storage, Fibre Channel SANs, or iSCSI SANs.
For more information on different types of storage, see ESX Server 3 Configuration Guide or ESX Server 3i Configuration Guide.
The type of storage device your ESX Server system has access to determines how you set up the VCB proxy and the transportation method Consolidated Backup uses to access virtual disk data.
Consolidated Backup provides the following methods of accessing virtual machine disk data:
• SAN Mode – Use with Fibre Channel and iSCSI storage to completely off-load backups to a physical VCB proxy.
• Hot-Add Mode – Use with any type of storage to perform backups by a VCB proxy set up in a virtual machine.
• LAN Mode (NBD Mode) – Use when your environment does not permit the use of the SAN or Hot-Add modes.

VMware Consolidated Backup Workflow
Before using Consolidated Backup, you need to configure and schedule a backup job for each virtual machine or a group of virtual machines.
At the scheduled time, the backup software starts the backup job on the VCB proxy. When the backup job is launched, the following steps take place:
1
The backup software calls the pre-backup script, which performs these tasks:
a
(Optional) Runs your custom pre-freeze script in the virtual machine.
The pre-freeze script prepares the critical software components in the virtual machine for a backup. See below Running Custom Quiescing Scripts.
b
Quiesces the virtual machine.
c
Puts the virtual machine into snapshot mode.
Changes to virtual disks are stored for later writing. The virtual machine can continue to operate during this process.
d
Unquiesces the virtual machine that was quiesced in Step b.
e
(Optional) Runs your custom post-thaw script in the virtual machine.
The post-thaw script reverses any changes made by the pre-freeze script in Step a.
f
Makes the virtual machine snapshot available to the third-party software:
•
For image-level virtual machine backups, see below Performing Image-Level Virtual Machine Backups.
•
For file-level backups of Microsoft Windows virtual machines, see below Performing File-Level Virtual Machine Backups.
2
The backup software performs an ordinary backup of the virtual machine snapshot moving the data to a backup medium. The virtual machine can continue to operate during this process.
3
The backup software calls the post-backup script, which performs the following tasks:
a
Unmounts the virtual machine snapshot from the backup proxy.
b
Takes the virtual machine out of snapshot mode, committing to disk any changes made while the machine was in snapshot mode.
