Snapshot
Use this option to create a snapshot of a volume. MegaRAID Recovery,
also known as Snapshot, offers a simplified way to recover data and
provides automatic protection for the boot volume. You can use the
Recovery feature to take a snapshot of a volume and to restore a
volume or file. Snapshot functionality allows you to capture data
changes to the volume, and, if data is deleted accidentally or

a previous point-in-time (PiT). MegaRAID Recovery supports up to eight
snapshots of PiTs for each volume.
