The ReadyDATA can provide protection of shares and LUNs through snapshots. Snapshots
contain references to data on a share or LUN. Strictly speaking, snapshots are not backups,
but they function as backups because you can recover data from snapshots.

You can take snapshots only of folders or LUNs. You cannot take a snapshot of a volume.
Snapshots reside on the same volume as the folder or LUN from which they were created.

The ReadyDATA can automatically take snapshots of a folder or LUN according to a
schedule that you specify. You can also manually take or delete individual snapshots at any
time. Depending on available storage space, you can keep an unlimited number of
snapshots.

If you configure both snapshots and continuous replication (see

Manage Replication and

Recovery Between Two or More Systems

on page

194), you have continuous protection.

WARNING:

When the available storage space on a volume decreases below
200

GB, or the consumed space is greater than 75 percent of total

capacity, the oldest automatic snapshots are automatically deleted
to bring the available storage space back to 200 GB or higher and
25 percent available space or higher. Manual snapshots are never
automatically deleted.

Once protection is available, the shares and LUNs on the Shares screen indicate the number
of snapshots and the number of days with protection (a share with daily protection is shown
on the left; a LUN with hourly protection is shown on the right):
