There are three types of schedules that you can set up to run automatically using
the snap sched command.
The following table describes the three types.
Type
Description
Weekly
Data ONTAP creates these Snapshot copies every Sunday at
midnight
Weekly Snapshot copies are called weekly.n, where n is an
integer. The most recent weekly Snapshot copy is weekly.0, and weekly.1 is the next most recent weekly Snapshot copy.
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 called nightly.n, where n is an integer. The most recent nightly Snapshot copy is nightly.0, and nightly.1 is the next most recent nightly Snapshot copy.
Hourly
Data ONTAP
creates these Snapshot copies on the hour or at
specified hours, except at midnight if a nightly or weekly
Snapshot copy is scheduled to occur at the same time.
Hourly Snapshot copies are called hourly.n, where n is an integer. The most recent hourly Snapshot copy is hourly.0, and hourly.1 is the next most recent hourly Snapshot copy.
Note: 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 higher the value of n, the older the Snapshot copy.
