To ensure that your data is protected regularly, schedule virtual machine (VM)
backups.
Before you begin
Before you back up VMs that are hosting Microsoft
Exchange Server databases, mount the databases.
By default, the maximum size allowed for a virtual hard disk (VHDX) in a backup operation is 2
TB. However, you can increase the maximum size to 8 TB by using the
vmmaxvirtualdisks option. For more information, see Vmmaxvirtualdisks.
About this task
During backup processing, Data Protection for Microsoft Hyper-V bypasses a guest Microsoft Exchange Server database
that is dismounted, corrupted, suspended, or not in a healthy state in a database availability group
(DAG). Databases in such invalid states are excluded from VM backups and are not available to
restore.

acceptor service is running on the data mover.
- If you are using the stand-alone scheduler, ensure that the scheduler service is running.
