VMware Virtual Machine Protection
9 October 2008
For a wide range of ESX Server virtual machines, VCB can accomplish two types of separate
backups of Guest VM data.
File Level
This type of VCB backup will result in the entire file system contents of the .vmdk
files to be mounted as local directory (i.e. mount point) on the VCB Windows 2003
Proxy Server that can then be protected by Backup Exec via a normal file system
backup of the VCB Proxy Server.
Image Level
This type of VCB backup will result in snapshot copies of the virtual machine .vmdk
files being copied from the ESX 3 server‟s VMFS volumes to the VCB Windows
2003 Proxy Server as complete .vmdk disk file images
These File Level or Image Level backups by can be done on a separate server from the ESX
server (i.e. “off-host“) using a centralized Windows 2003 machine as the off-host VCB “Proxy”
Server. VCB is then used by Backup Exec, via pre\post job “scripts”, during a backup of an ESX
server to perform File Level or Image Level (or a combination) backup of the guest virtual
machines by exporting either the File Level data or complete Image Level data (.vmdk, .vmx,
and .log files) to the off-host Windows 2003 Proxy Server. (see Figure 4- VCB Proxy Server
Backup Configuration)
