Managing snapshots

A snapshot is a point-in-time copy of an operating system volume. It sets up a link between the source volume and the underlying logical devices in an external storage enclosure. When data on the source volume changes, the differences are captured on the snapshot drive, maintaining the data as it looked when the snapshot was created. You can use the snapshot for tape backup, drive cloning, and multi-server rollout.

Working with snapshots

The Snapshot wizard guides you through all of the steps necessary to create a snapshot. Each snapshot creates a backup of one or more volumes, called a snapshot set. You cannot perform any actions on the individual snapshots in a snapshot set. To delete or mount a snapshot, for example, you must use the appropriate action on the Snapshot set object, in the Snapshots view.

When you create a snapshot, you can run the job immediately or schedule it for a later date and time. Use the Schedule Manager, in the management service agent console, to monitor and manage scheduled jobs.

Snapshot size

Adaptec Storage Manager displays different size values for a snapshot and its underlying logical devices, depending on the situation:
