BA seems to be using space on a VM its backing up

[cracker666]

We backup our 2012 r2 Host system which has 5 VM's on D drive to a USB3 HDD
our BA is at version 9.5.1r1
We do a full Vss mode backup leaving out pagefiles external drives, but including exchange.

The problem I have is this, When we do a back up BA seems to be using space on a VM its backing up, is this possible.
The BA instance is only on the host not this effected VM.
We went from 300gb free space to 10gb in one day.
Its only started to do this since Thursday.

Any ideas how I can track this down.

Hi

we have the same issue has started, not sure if latest release (which already has a know issue with showing files in a guest VM) or cause we have started doing a granular exchange backup
we have AVHDX being created which would be for a checkpoint for backing up but seems to me they should be merged when the backup is complete
we have upgraded to same version

shutting down the guest VM's' will cause the merge to happen and get the disk space back but we should not be having this issue

have you checked if you have AVHDX files as well being created?

Backup just started AVHDX file created, happens each time backup runs a new AVFDH is created I get why
but it cant just leave them like this?
