Environment



NetBackup 7.1.0.2 using VMware backup agent.
 


Cause



Note the following about block level incremental backups:

- Works only with ESX 4.0 virtual machines at version vmx-07 or later.
- Requires the FlashBackup-Windows policy type.
- Works only with backups of the entire virtual machine (does not apply to backups that specify individual files).
- Requires vStorage (cannot be used in VCB-based backups).
 

For more information see the link below for the article "About reducing the size of VMware Backups."


Solution



1. Open the VMware policy, go to the clients tab, and review the column labeled "Hardware".

2.  Any virtual machine not identified as vmx-07 or higher is incompatible with the Block-Level Incremental Backup feature.  To resolve this issue choose one of the following options:

a) If these VMs are on ESX 4.x or higher, upgrade the virtual machine hardware to version 7 or higher (refer to appropriate VMware documentation).

b)  Move all vmx-04 virtual machines into a separate backup policy and disable the Block-Level Incremental Backup (BLIB) option.
