NetBackup 7 for VMware making full backups instead of incremental
I just recently upgraded from NetBackup 6.5.4 to NetBackup 7 on Windows Server 2008. I have daily incremental backups scheduled but NetBackup makes full backups instead. The details of my infrastructure are as follows:
ESX4i Update 1
IBM DS4700 FC SAN
All virtual machines are version 7
The virtual machines being backed up are all Windows Server 2003 or 2008.
There are no RDMs and all virtual disks are think provisioned.
I am using the vStorage API and not VCB for the backups.
The policy settings are:
Policy type - Flashbackup-Windows
Perform Block Level Incremental backups - Checked
Perform Snapshot Backups - Checked (But greyed out)
Perform Off-Host Backups - Checked
Client Name Selection - VM Display Name
Virtual Machine Backup - Mapped Full VM
Transfer Type - San
Virtual Machine Quiesce - Enabled
Exclude Empty and Deleted Blocks - Enabled
Existing Snapshot Handling - Remove NBU
Monolithic Export (VCB Only) - Disabled
Snapshot Mount Point (VCB Only) - Empty
I am backing up to disk then duplicating to tape.
I created new policies and tried both Cumulative and Differential but I always get full backups.
I also checked the virtual machines and "Changed Block Tracking" is enabled.
Thats all I can think of. Any ideas?
