Always-On-Group Support for MSSQL for "SQL DB Exclusions"

[Patschi]

Basically Veeam works very well when backuping up MSSQL 2014 nodes, but when you're having the vCenter database also running on the same AOG, I ran into the problem that Veeam wasn't able to backup the machines because of the VSS error “VSSControl: Failed to freeze guest, wait timeout”:


Ofcourse the database was added to the "SQL Databases Exclusions"-list, but this did change nothing - it just keeps failing and failing: (Veeam detected the DB data itself fully automatically)


After investigating the problem further, I finally found out (more detailed in german language on my site http://pkern.at/veeam-vsscontrol-failed ... it-timeout), that Veeam seems not to be able to understand, that there is a AOG behind the DNS name in the exclusions list. So when I manually add the nodes behind that Always-On-Group manually to the list, like that:


After that the backups works fine again!

I don't know if this is just an issue on my side, an already known issue, or any sort of a bug, but I wanted to share it in the Veeam forum anyway. Maybe someone runs also into a similiar issue someday...

Patrik, thanks for paying our attention to this. You've applied a valid workaround, however databases detection/exclusion mechanism should be improved to address this scenario, so this will be tracked as a requirement for future versions. Thanks.

My pleasure! I just realized it after creating the topic: Maybe this thread would better fit in the sub-forum for VMware vSphere, because this issue is just related to the VMware vCenter anyway.

No problem, I've moved the thread. Thanks again for the heads up.
