Hi,
I have a SQL Server 2012 AlwaysOn Availability Group which uses Veeam 7 for backups. I'm using a 2 node Windows 2012 cluster with a file share witness.
- At 19:00 the primary node is backed up by Veeam using application aware image processing to truncate the logs.
- At 22:00 the secondary node is backed up using Veeam without application aware image processing.
On the primary node, I see application event log error "backup command failed to complete BACKUP LOG" <model/master/tempdb/YourDB> "Check the backup application log for detailed information".
On the secondary node, I see application event log error "The recovery LSN (45:6543:1) was identified with the ID 5.This is an informational message only. No user interaction is required"
Other than the backup related messages, the AlwaysON SQL cluster is fine - cluster validation checks pass as expected, no other errors are logged in the event log and failover works as expected.
I want to backup the active DB on my AAG and truncate the logs - ideally using Veeam, but if not, I'm happy to use an alternative.
Is there a best practice, recommended way of doing this?
Thanks
