I've been backing up SQL server AlwaysON systems with a single backup job. Thus the same job backing up all the nodes in the availability group to the same repository.
I notice that the backup job realizes what node is active and tends to do log backups and log truncation on the active node.
Now I'm wandering, would it introduce any problems if I use one backupjob per node instead of one job with all the nodes. Is there something with Veeam that says if you are backing up AlwaysON that all the nodes need to belong to the same backup job? If so, I don't find it. And if it's not so I'm considering changing the backup strategy and have multiple backupjobs for AlwaysON systems.
