Exchange 2010 backups failing

Hi all,

I have Exchange 2010 SP3 on vmware and we have been using Veeam for the last 2 years. We recently upgraded from SP1 to SP3 in our Exchange and after a couple of weeks, the backups have started to fail. They are successful if I turn VSS off but I know there is no point in doing that. I even rebooted the server but still no luck. Any idea what could be the problem ?

What does the Veeam log report?

Did you try spend time on the support site

How is your exchange environment setup?

If you are in DAG, the server that  you are trying to backup hold an active DB Copy? If so move that copy to another, backup a server that does not have an active DB Copy... you should not have any problems and the logs will truncate..

Unable to release guest. Details: VSSControl: Failed to freeze guest, wait timeout

This is what Veeam tells and after 3 retries, it stops.
Exchange UserSystems AdministratorAuthor Commented:
Yes I do have a DAG and the databases are spread by activation preference.

Ok I will try doing like this tonight.

Do you have a server that only holds passive copies?

We use veeam as well and we had issues with the backups completing successfully and truncating the log files with active copies... VSS kept on crashing..  Our DAG has 3 multirole servers... preferences of 1 & 2 were giving to the first two servers and preference of 3 for all copies were given to the 3rd server.. backup is only done on the 3rd server... I have not had an issues in 2 years with this approach

This will work but you shouldn't have to do this, if it is something you choose to do make sure that the log files are getting truncated on your active copies after the backup completes
