Backup hangs on Server 2012

Post by tromsonoc » Aug 06, 2013 6:18 am

Hi

Lately we have been experiencing trouble with one of our customers.
The backupjob is set to take backup on 2 servers: Server 2008R2 and 2012.

The 2008R2 is done in a few minutes, but the backup of the 2012 server is currently approaching a week

I have recreated the backupjob multiple times, and i have set the timeout to 30 mins.
Last time when i waited for the actual error message it took 1,5 months.

Error:
Failed to prepare guest for hot backup. Error: VSSControl: Failed to prepare guest for freeze, wait timeout 18875 sec
Error: VSSControl: Failed to prepare guest for freeze, wait timeout 18875 sec

Timeout is set to 1800000.

Best regards,
TN

What kind of VM it is (does it hold SQL Server, for example)? Could you check the VSS writers state by running the following command within the guest OS:

Code: Select all

vssadmin list writers
Do you have something related in the Windows Events Log? Have you ever contacted Veeam support with this?

Hi, Tromso. Can it also be that this VM is a vCenter machine with locally attached SQL database, or just a machine that apart from DC hosts a vCenter database?

Thanks.

Hi

Thanks the for the replies.

No it doesnt hold any databases, its only a DC.

I tried the "vssadmin list writers", but it didn't work. VSS is not enabled on any of the drives.
Nothing in the event log about the backup either.

What do you mean by "didn't work"? What was the output of this command?

Didn't get any output, it just hanged.
However, i found out that the VSS service had stopped. Though i experienced another problem when i tried to start it again.

Im gonna reboot when the customer leaves work today. Got error 1053 in services.

Generally, there's no need to enable anything manually. I would recommend to open a case with technical support, as it is advised for any technical issue. Logs should definitely tell more information of why the VM cannot be backed up normally.

Case solved

Had to delete the VeeamVssSupport folder and let Veeam recreate it.
(C:\Windows\VeeamVssSupport)
