Backup strategies

Depending on your specific requirements that regard network traffic, backup window, and acceptable restore times, you might choose to follow different backup strategies. It is important to understand all aspects of Exchange Server disaster recovery, and backup considerations that are recommended by Microsoft. Refer to your Exchange Server documentation for this information.

When you consider backup strategies, use the following guidelines:

Do not use incremental and differential backups together.
If you choose a strategy that involves incremental or differential backups, circular logging must be disabled on the databases of the Exchange Server.
Consider applying DAG database replication technologies. Refer to your Microsoft documentation for details that regard this technology.
For another Database Availability Group (DAG) backup strategy, set up all DAG members to back up all of the database copies. Use the /MIN and /PREFERDAGPAS flags.
