Parameters

snapshot_name

Specifies the name of an existing snapshot to use as the base snapshot. The name specified can be a snapshot name, such as vol1_snap, or it can be the name of a scheduled NetApp backup that has a name like nightly.x, where x is the sequence number (where nightly.0 is the oldest snapshot).

You can also use a pattern with wildcard characters to select a snapshot. The wildcard characters can be either of the following:

*

An asterisk (*) matches any character.

?

A question mark (?) matches a single character.

The wildcards are useful if your snapshots follow a pattern, such as including the date or data and time as part of the snapshot name. For example, a snapshot created on November 12 2012 at 11:10:00 AM could be saved as UserDataVol_121103111000_snapshot. The most recent snapshot that matches the pattern is selected as the existing base. For example, if there are two saved snapshots (UserDataVol_121103111000_snapshot and UserDataVol_121103231000_snapshot, the UserDataVol_121103231100_snapshot is selected because it is 12 hours newer than the other snapshot.

-basesnapshotname="UserDataVol_*_snapshot"

Question marks work well for scheduled backups that follow a consistent name pattern. This syntax selects the latest "nightly" backup as the snapshot to use as the existing base.
