Veeam Backup failed with error

[roopeshm]

In my veeam backup replication there is a backup failed with the below error.

"3/20/2024 1:12:19 PM :: Processing AD-DC1 Error: An error occurred while quiescing the virtual machine. See the virtual machine's event log for details. (An error occurred while saving the snapshot: Failed to quiesce the virtual machine., An error occurred while taking a snapshot: Failed to quiesce the virtual machine.)" Upon checking i found the veeam unable to create snapshot.

So i went to vcenter and tried to start the  quiesced snapshot and i got error. Checked the VM logs in vcenter found.
VssSyncStart' operation failed: IDispatch error #8449 (0x80042301). I have checked the VM tools service and VSS writers state everything is okay,

No clues about the VM, about the vSphere version, the Veeam version, or whether you have done research on the Veeam forums?

Hi,

it will be the post it to the Team forums as mentioned above, but I can tell you that the most problems with backup is that you have snapshots on the VM's and they to the problems. Only vCenter is an exception and for it is its special backup and restore procedure.
