Types of user-specified Snapshot copy schedules

You can configure weekly, nightly, or hourly Snapshot copy schedules by using the snap sched command.

The following table describes the available types of Snapshot copy schedules:

Type Description
Weekly Data ONTAP creates these Snapshot copies every Sunday at midnight.

Weekly Snapshot copies are named weekly.n, where n is an integer. The most recent weekly Snapshot copy is weekly.0, the next most recent weekly Snapshot copy is weekly.1, and so on.

Nightly Data ONTAP creates these Snapshot copies every night at midnight, except when a weekly Snapshot copy is scheduled to occur at the same time.

Nightly Snapshot copies are named nightly.n, where n is an integer. The most recent nightly Snapshot copy is nightly.0, nightly.1 is the next most recent nightly Snapshot copy, and so on.

Hourly Data ONTAP creates these Snapshot copies on the hour or at specified hours, except if a weekly or nightly Snapshot copy is scheduled to occur at the same time.

Hourly Snapshot copies are named hourly.n, where n is an integer. The most recent hourly Snapshot copy is hourly.0, hourly.0 is the next most recent hourly Snapshot copy, and so on.

When Data ONTAP creates a weekly, nightly, or hourly Snapshot copy, the value of n is adjusted for all the weekly, nightly, or hourly Snapshot copies; the earlier Snapshot copies in the series are renamed. The higher the value of n, the older the Snapshot copy.
