[Acronis for VMware 9.2.10571] - Failed to quiesce the virtual machine, but only on one host
I have a vCenter 6.0 with two hosts (both ESXi 6.0.0, 3825889). Using ABVM 9.2.10571, all guests on the first host are backed up without issue. However, any running Windows guests on the 2nd host are not backed up with this error:
Error code: 32
Message: Awaiting task 'CreateSnapshot' has failed. Reason: An error occurred while saving the snapshot: Failed to quiesce the virtual machine..
VMTools is up to date on all guests.
If the Windows guests are suspended or shutdown, there is no issue. The backup completes successfully.
Non-Windows guests are not affected and are backed up whether running or not.
I've resorted to scripting "suspend" on all affected guests while the backup runs, and although this is not ideal, it does get around the issue.
Does anyone have a reason or solution for the issue? Is there some particular configuration setting on the host I may be overlooking?
Thanks in advance
