Best Practices for a Myriad Backup

Segregate your business-critical data in a separate Myriad file system to optimize recovery time objective (RTO) and recovery point objective (RPO). To keep RTO as short as possible and allow optimal RPO, segregate business critical data in a separate Myriad file system. By backing up and recovering this critical subset of data independently, backups can be taken more frequently and recovered more quickly.

Use snapshots to ensure a complete, coherent, point-in-time backup of business-critical data. With the "always on" nature of Myriad, the best way to ensure a complete, coherent, point-in-time backup is to take a snapshot of your Myriad file system, back it up, then delete it (see Add or Delete a Snapshot).

Note: If you attempt to back up the file system directly, you run the risk of files changing during your backup.

Develop and practice your disaster recovery procedure in advance of any disaster situation. While backups are a critical element of a disaster recovery strategy, backups alone are insufficient. Depending on the scope of the disaster, you might also need to record:

• The configuration (for example, size, name, share definitions, and so on) of the file system to recover to.

• The population of users that had access to the file system, and the details of that access.

• The clients that use the file system and their configurations (for example, mount points, mount options, and so on).

Quantum strongly recommends you practice your disaster recovery procedure at a convenient time of your choosing, in preparation for disaster situations.
