Netgear EDA 500 User Manual

The ReadyNAS OS 6.1 uses Smart Snapshot Management to reduce the number of automatic (continuous)
snapshots per shared folder or LUN. Every hour, this feature automatically prunes older hourly, daily, and
weekly snapshots, according to the following rules:

Hourly snapshots are kept for 48 hours.

Daily snapshots are kept for four weeks.

Weekly snapshots are kept for eight weeks.

The Smart Snapshot Management feature does not prune manual snapshots.

You can replace a shared folder or LUN with an earlier version by rolling back to a snapshot. When you
roll back to a snapshot, the entire shared folder or LUN is replaced with the version captured by the
snapshot. All snapshots that were taken after the snapshot that was used for rolling back are deleted. For
information about how to roll back to a snapshot, see 

 on page 116.

You can copy a snapshot to become a new independent shared folder or LUN. Changes made to the
clone do not affect the parent shared folder or LUN (“origin”) and changes made to the parent do not affect
the clone. For information about how to clone snapshots, see 

 on page 121.

You can manually take snapshots from the Shares screen and the Timeline screen. The following procedure
describes how to take snapshots from the Shares screen.

Select Shares > Shares.
A list of shared folders and LUNs on each volume displays.

Select the shared folder or LUN that you want to take a snapshot of.

From the pop-up menu that displays, select Snapshot.
