(Snapshot)-Related Options
The commands in this section are used to perform actions with the Recovery advanced
software, also known as Snapshot (LSIP200038104).
The Recovery feature uses Snapshot technology to offer a simplified way to recover lost
data and provides protection for any volume, including the boot volume. You can use
the Recovery feature to take snapshots of a volume at designated point-in-time (PiT)
and restore the volume or files from those points in case data is deleted, whether
accidentally or maliciously. MegaRAID Recovery supports up to 8 snapshots of PiTs for
each volume.
