- OBM version 6.11.0.0 or above is installed on all Exchange node with Mailbox role.
- Since 6.11.0.0, the Exchange server 2010 backup will no longer require to spool the database to the hard disk, however the VSS Exchange backup still requires certain amount of disk space to operate. Microsoft suggested that some shadow copy mechanism may require to reserve 100% of the original database.

- It is recommended that the temporary directory be configured on a local drive.
- For domain controller with Active Directory installed, a System State backup must be performed regularly with the MS Exchange servers (DAG) backup.
- Scheduled backup is required, as all the OBM on different Exchange servers will base on the scheduled backup time to activate all the backups at the same time, even all these Exchange servers are located at different timezones. When the backup on all Exchange servers are finished, a single email report will be generated.
The scheduler would refers to the timezone setting of the corresponding OBM account's profile (instead of the system clock on the client machine for stand-alone Exchange server backup).
Manual / Local Copy and seed load are not considered as a complete Exchange DAG backup, as the job ran on individual Exchange DAG member, passive database copy(s) were skipped.
- The backup module protects the Exchange database level, if full system backup is required, please run the full system backup on each Exchange server within the DAG.
- To backup mailbox database within an Exchange DAG, OBM is required to be installed on each DAG member with Mailbox Role (e.g. servers that are hosting the mailbox databases). It is not necessary to install OBM on Exchange server with CAS (Client Access Server) Role only.
