By default, snapshots are configured automaticly at fixed hour and date by Data ONTAP. There are snapshots for the aggregates and for the volumes. To display the list of snapshots for the aggregates: snap list -A To display the list of snapshots for the volumes: snap list -V (“-V” is optionnal because it is the default option) To display the snapshots’ schedule: snap sched [-A|-V] (“-A”: aggregate – “-V”: volume) With the last command, we get an output like: Volume vol0: 0 2 6@8,12,16,20 This can be translated by: 0 preserved/created weekly snapshot – 2 preserved daily snapshots – 6 preserved hourly snapshots. The hourly snapshot are created at 8:00, 12:00, 16:00 and 20:00. The weekly snapshots are created at midnight every Sunday. The daily snapshots are created every day at midnight every day except Sunday.
