About Instant Recovery
This feature makes backups available for quick recovery from disk. Instant Recovery combines snapshot technology - the image is created with minimal interruption of user access to data - with the ability to do rapid snapshot-based restores. The snapshot is retained on disk as a full backup image. The snapshot can also be the source for an additional backup copy to tape or other storage.
Instant Recovery makes possible three additional variations of restore: block-level restore, file promotion, and snapshot rollback.
