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.
