What the snap sched command arguments mean

The snap sched command arguments allow you to specify the schedule for creating Snapshot copies. You can also specify the number of Snapshot copies to be retained.

The following illustration explains the arguments in a sample snap sched command output:

Arguments in a sample snap sched command output

Snapshot copy schedule results: The command shown in the illustration keeps the two most recent weekly Snapshot copies, the six most recent nightly Snapshot copies, and the eight most recent hourly Snapshot copies, created at 8 a.m., 12 p.m., 4 p.m., and 8 p.m. every day. Whenever the Snapshot copy schedule creates a new Snapshot copy of a particular type, it deletes the oldest Snapshot copy and renames the existing Snapshot copies. On the hour, for example, the system deletes hourly.7, renames hourly.0 to hourly.1, and so on.
Note: If you omit the @ argument specifying the hours for the hourly Snapshot copies, Data ONTAP creates a Snapshot copy every hour. Nightly and weekly Snapshot copies are always created at midnight.
