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
maliciously, restore the data from the view or roll back to a snapshot at
a previous point-in-time (PiT). MegaRAID Recovery supports up to eight
snapshots of PiTs for each volume.
