Hi everyone! Does someone know how to solve the problem with backup? I have Exchange failover cluster (2 Exchange Server 2013) on Proxmox VE. When backup job starts I get error on Exch servers

Hi,

do you use qemu-guest-agent in these VMs?

What PVE version do you use?
 
Does the VSS in the VMs triggers if the backup starts?
I don't know Exchange but I guess it is the freeze of the fs that produce the Error.
Disable the qemu-guest-agent and test again.

Keep in mind if qemu-guest-agent is disabled the OS does not flush the caches and the Backup may not consistent.
