Smart Snapshot Management 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. Note: The Smart Snapshot Management feature does not prune manual snapshots. Rolling Back 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 Roll Back to a Snapshot on page 133. Clones 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 Clone Snapshots on page 139. Snapshots 127
