VDR CBT not working (Incremental)

[mhost]

Hi,

I'm using VDR 2.0 on ESXi 5.0 to backup some VMs on a test host (whitebox)

This has worked fine - all backups being incremental.

Recently I had a host-side crash where a disk became inaccessible.

Suddenly a specific VM backup only runs as full backup - whereas it was incremental (and much faster) before.

The VM is a Server 2008 R2, hardware version 8.0 and with updated VM Tools.

It seems like Changed Block Tracking does not work for the VM anymore.

I have tried reinstalling tools for the VM - no luck.

Any other suggestions?

BTW: It has yet to finish a full backup - would it help, if I let it complete?

Best regards

Martin

UPDATE 7. OCT: Nevermind... After a full backup (which took a looong time), incremental back was running again. I guess that the .cbt file was damaged during the crash - and fixed/updated by running a full backup..

Good to read there was an explanation on what happened
