The MegaRAID Recovery feature, also known as Snapshot, offers a simplified way to recover
data and provides automatic protection for the boot volume. You can use MegaRAID
Recovery to take a snapshot of a volume and to restore a volume or file.
Snapshot functionality allows users to capture data changes to the volume. If data is deleted
accidentally or maliciously, you can restore the data from view or roll back to a snapshot at a
previous Point in Time (PiT).
You can make up to 8 snapshots of Point in Times for each volume.
You can either restore files or roll back applications to a previous point in time.
Recovers lost data from disk in minutes, minimizing the downtime experienced by users and
eliminating the lengthy process of restoring data from tape.
Allows isolation of a server’s boot volume to a separate virtual drive; by enabling the Auto
Snapshot feature, users are guaranteed that bootable snapshots exist, in case corruption of
operating system occurs.
Note: MegaRAID Recovery Snapshots are not a substitute for a tested backup strategy.
When Recovery Snapshot is enabled, changes to the selected volume are tracked.
When a roll back to a snapshot at a previous Point in Time (PiT) is done, you are
“undoing” changes to the volume that caused corruption or a file deletion. The
first snapshot does not create a full volume backup. Recovery Snapshot is
equivalent to Microsoft* System Restore with additional features and capabilities.
Detailed Configuration steps are as below:
1. Select the Logical view. Select and highlight a virtual drive from the list of virtual
drives (If required, initialize, allocate and format the virtual drive).
2. Select Go To -> Virtual Drive -> Enable MegaRAID Recovery on the menu bar.
