SQL Always On cluster: What happens with the T-Log backup chain when the cluster performs a failover

[dbeerts]

Hi,

An old case came into my mind where Veeam support told me this:
if a cluster performs a failover between the image-level backups, VBR will not detect the change in configuration, resulting in the Log backups addressing wrong nodes for the database T-log backups.

My question is:
Has this been fixed in new versions?
Or what is best practice when you are patching nodes of the failover cluster and you don't want to lose a whole day of T-log backups and a new image backup isn't an option?

Hello,
and welcome to the forum. Can you please share the case number for further investigations?

Best regards,

Hi Dries, to proceed with logs backup after failover, new VM image-level backup is required. The best practice would be to plan the VM backup as a part of nodes maintenance.
