ReadyNAS OS 6.2

Basic Snapshot Concepts

The ReadyNAS can provide protection of shared folders and LUNs through snapshots. Snapshots contain references to data on a shared folder 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 shared folders or LUNs. You cannot take a snapshot of a volume. Snapshots reside on the same volume as the shared folder or LUN from which they were created.

Note: Snapshots are not supported for the home folders that the ReadyNAS automatically creates for each user. For more information about home folders, see User and Group Account Limitations on page 131.

The ReadyNAS can automatically take snapshots of a shared 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.

WARNING:

When the available storage space on a volume decreases below five percent of the volume’s total storage space, the oldest automatic snapshots are automatically deleted to bring the available storage space back to 5 percent or higher. Manual snapshots are never automatically deleted.

Once protection is available, the shared folders and LUNs on the Shares screen indicate the number of snapshots and the number of days with protection.

Note: For snapshots to be accessible to users from their network-attached device, you must to select the Allow snapshot access check box in the shared folder or LUN settings pop-up screen. For more information, see View and Change the Properties of a Shared Folder on page 44.
