Email backups must meet schedule and storage requirements.

Hardware failures or other (sometimes physical) disasters can cause data loss to active applications, and precipitate the need for expedient recovery. Ensuring backups are conducted on an agreed schedule creates a timely copy from which to recover active systems. Storing backup contents at a separate physical location protects the backup data from site-specific physical disasters. Backup schedule and storage location are determined in accordance with the MAC category and confidentiality level of the system.
