I am backing up my Cloud environment with Avamar and to fix a issue with vCloud Director, I need to disable CBT on the VM. What impact will it have on my Avamar backups ?

Resolution

To work around this issue, disable CBT on the virtual machine.

Caution: Disabling CBT may cause issues with your backup software as most solutions require CBT for optimal performance. Engage your backup solution vendor for any implications on disabling.

Does Avamar uses the CBT in the VM or its own CBT to backup using de-duplication method ?
