Hi Adrian, Do you have application-aware image processing enabled for these VMs? If yes, do you see guest VMs failing to engage VSS with some errors like Guest processing skipped ? By the way, is Hot-Add transport mode is used? If yes, do these VMs have IDE drives? Thanks!

Do you have Windows 2012 R2 on your Hyper-V by any chance? Also, does any of your VMs actually get suspended during backup? If so, then please do the following:
1. Add SCSI adapter to your VM 2. Make sure that you have integration services installed and try to restart Volume Shadow Copy Requestor service 3. Make sure that “Backup (Volume Snapshot)” option is enabled within the VM settings
