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.

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 

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
