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
