You can perform backups from the command line interface.
What Is Backed Up

What Is Not Backed Up
- System state data
- Active Directory data
- Personal Information Stores (PST files)
- Personal Address Books
- Offline folders
These items can be backed up using the Windows File System Agent.
Database Failover or an Unavailable Database
If a database failover occurs in a DAG environment or if the database becomes unavailable in a standard environment during a backup, the backup of that database fails, but the overall backup job continues. In this case, the backup reverts to full for the failed database during the next backup.
If a failover occurs or if the database becomes unavailable in the middle of a cycle, the next backup remains an incremental backup.
