When backing up an SQL 2016 Basic always-on cluster, application aware backups can only be made from the primary node. I know this is a limitation imposed by Micro$oft. But it would in some cases be useful to have the option to switch to image level backup mode for secondary database cluster nodes.
But also more in general, as @DonZoomik pointed out in a related post (veeam-backup-replication-f2/5-missing-f ... ml#p263378) :
To which @Foggy replied:"Is AAP/VSS is having a bad day, you could eventually just do a crash-consistent backup (VM snapshot without any integrations), it's better than nothing."
However, I would still like Veeam to go through all retries and only fail-over as a last resort."If you set AAIP to ignore failures, the job will fail over to crash-consistent backup"
