Changed Block Tracking

[Baldy27]

Hi,

When i am processing a backup i get the error "Changed Block tracking can not be enabled, one or more snapshots preset."

Only 1 VM from 11 in that batch has this issue.

Any ideas?

Thanks

Chris, does this VM have any existing snapshots? If yes, you need to consolidate it to enable CBT.

Sorry im now to Veeam, where would the existing snapshots be located?

Right-click the VM in vSphere client and open Snapshot Manager to view existing snapshots.

Nice one, i've consolidated them, just going to rerun the. Job

Consolidated the Snapshots but still get the same error

[Baldy27]

Deleted totally now, re running

Thanks for the advise, this worked perfect.

Quick question ...

If a Snapshot is taken of the VM, then our backup runs and gives us the Warning "Changed Block tracking can not be enabled, one or more snapshots preset."

Does this mean a full backup of the VM was performed, therefore taking more space up on our server ?

Nope, it only illustrates the fact that our own proprietary mechanism has been used to detect changes. Since it needs to scan a whole VM, backup time will be increased. Thanks.
