Managing Snapshot Profiles
A Snapshot Profile is a collection of rules describing when to take periodic snapshots for one or more volumes and the time at
which snapshots are deleted (expired).
A snapshot is a point-in-time copy (PITC) of one or more volumes. Storage Center snapshots differ from traditional snapshots/
PITCs because blocks of data or pages are frozen and not copied. No user data is moved, making the process efficient in both
time taken to complete the snapshot, and space used by snapshots.
NOTE:
If two or more snapshots are scheduled to be created at the same time for a given volume, the Storage Center
creates only one snapshot. The snapshot that has the longest expiration time is created, and the other scheduled snapshots
are ignored.
