These items can be backed up using the Windows File System Agent.

Database Failures, an Unavailable Database, or Database Failover

A database failure could occur during a backup in a DAG environment for several reasons (for example, the database copy becomes unavailable, or the connection to the network is lost). In this case, the backup of the database fails, but the overall backup job continues. During the next incremental backup, the backup of the failed database reverts to a full backup.

However, if a database failure occurs in the middle of a cycle, the next backup job remains an incremental backup.
