Backing Up Your Data with Snapshots

Adaptec Storage Manager's snapshot feature creates application-consistent snapshots of your storage space for backup purposes. Snapshots are “pictures” of your data at a particular point in time. A snapshot sets up a link between one logical device in your storage space (the "source") and another logical device in your storage space (the "target"). When data on the source drive changes, the differences are captured on the snapshot drive.

If an error occurs on the logical device, you can roll back the data to the point in time when the snapshot was created. You can also use snapshots for tape backup, drive cloning, and multi-server roll-out.

There are two snapshot options: Snapshot Backup — copies all data on a logical device so that it can be moved from one server to another; and Snapshot Nobackup — creates a temporary copy of a logical device for tape backup and reference (uses less system resources than Snapshot Backup).
