Introduction This document describes the VCBimage backup method in optimized mode. HP Data Protector Software provides a complete solution for backing up a VMware virtual Infrastructure environment. The virtual machines (VMs), ESX server console and also VirtualCenter (VC) configuration database can be backed up using Data Protector.

Backup There is a new omnirc variable named OB2_VMWARE_VCBOPTIMISED. During backup this variable must be set to 1 on the VCB proxy server, which causes vcbMounter to be executed with –F=0 and –M=0 options. Here the virtual machine disk files copied to the proxy server are optimized and also split into multiple files of size less than 2 GB. Unused space in the file system will not be copied. Backup time is shorter and tape space is used more efficiently.

– ESX server 2: esx2.company.com – VCB proxy server: vcbproxy1.company.com – Cell manager: yuppie.company.com You have taken the VCBimage backup of VMs (from ESX server 1) in optimized mode, by selecting the VC server (virtualcenter1.company.com) as backup client when configuring the backup specification. To restore the session, go to the restore context in the Data Protector GUI as in Figure 1. In the Scoping Pane, expand VMware, expand virtualcenter1.company.

variables will take longer, because after restoring the files to the temporary location, the vcbRestore utility will be called to convert the disk files. Important: Restore of optimized backup without setting the omnirc variable OB2_VMWARE_VCBOPTIMISED will not result in any error during restore. However, it will not be possible to register the VM, as the disk files restored are not flat vmdk files.
