What a Snapshot copy is

A Snapshot copy is a read-only image of a traditional or FlexVol volume, or an aggregate, that captures the state of the file system at a point in time. Data ONTAP maintains a configurable Snapshot copy schedule that creates and deletes Snapshot copies automatically for each volume. You can also create and delete Snapshot copies manually.

For information about traditional or FlexVol volumes or aggregates, see the Data ONTAP Storage Management Guide for 7-Mode.

You can store up to 255 manually initiated Snapshot copies at one time on each volume or up to 254 scheduled Snapshot copies.

You can specify the percentage of disk space that Snapshot copies can occupy. The default setting is 5 percent of the total (both used and unused) space on the disk for a FlexVol volume and 0 percent for aggregates.
