Hello
Since upgrading our environment from 5.0 to 5.1 we are having problems backing up several VM's
We use the Netvault Backup, with the VMware Plugin, to backup our VM's
When a backup job is run overnight, one VM fails, with the following message:
Task to create VM snapshot failed with reason 'An error occurred while quiescing the virtual machine. See the virtual machine's event log for details.'
I check the VM's event log and the following is displayed
The guest OS has reported an error during quiescing. The error code was: 4 The error message was: Quiesce aborted.
The following is what I have tried to fix the problem, all failed:
- Remove and reinstall VMware Tools on the VM approx 5 times in a row
- Remove VMware Tools and reinstall without the VSS option
- Disable VSS backup from within Netvault
- Manual snapshot of the VM will sometimes work and sometimes fail
We have a backup job that runs every night Monday - THursday, which backs up approx 10 VM's, with 1 failing with the error message.
On a Friday night we have 2 backups jobs that run, which backup a total of approx 30 VM's, with 7 VM's failing with the error message
Any ideas how I can fix this problem? It's been suggested its something to do with Datastore storms but everything was working before the upgrade to 5.1
Thanks in advance
Andrew
