Backup Exec 2012: Hyper-V differential backups and fixed disk issue?

This issue has been solved. See solution.

Hello all,

just a quick inquiry if I'm on the right track: is it possible that Differential/Incremental Backups won't work (fall back to full) for a Hyper-V-VM which is using fixed disks (fixed size VHDs)?

I'm currently experiencing this issue in my backups. Is there any tweak / workaround for this available, or do I have to live with it for the time being?

Thanks in advance, Manuel

Yes, that's right. For fixed sized disks, Backup Exec cannot calculate the used blocks/sectors from the VHD for incremental or differential backups.

Thanks - perhaps room for future improvement? Perhaps the agent can help to collect that info in a future release - or Microsoft adds that feature...
