Staged backup
Snapshots can be used for a variety of purposes, including: To allow the primary volume to be rolled back to a “known good” copy of the data in the event that the primary volume is corrupted To create complete replica of production data for online analytical processing or data mining To create a snapshot of production data for batch processes such as end-of-day or end-of-year reporting, where a stable and consistent data copy is required To facilitate data migrations To replicate production data for development and testing As the secondary stage in a staged tape backup or remote mirroring process
