Smart Snapshot Management
ReadyNAS OS 6.1 and later uses Smart Snapshot Management to reduce the number
of automatic (continuous) snapshots per share 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.
Monthly snapshots are kept for as long as there is sufficient capacity. (The last weekly
snapshot in a month becomes the monthly snapshot for that month.)
Note: The Smart Snapshot Management feature does not prune manual snapshots.
Rolling Back
You can replace a share or LUN with an earlier version by rolling back to a snapshot.
When you roll back to a snapshot, the entire share 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 Using Recovery Mode on page 130.
Clones
You can copy a snapshot to become a new independent share or LUN. Changes made
to the clone do not affect the parent share or LUN and changes made to the parent do
not affect the clone. For information about how to clone snapshots, see Clone Snapshots
on page 131.
