Restoring Data From the Backup
You can restore the data from the backup by performing a Rapid Restore from the disk snapshot or by copying the data from a backup tape.
The fastest and most efficient way to restore data is with a Rapid Restore of the data. This is the same data that was last saved to tape. The snapshot can be mounted directly on the production server, and data or individual files can be copied directly from the snapshot to the production file systems. Additionally, the Instant Image software can, if desired, restore the entire set, group, or individual volumes by copying only the data that was modified since the last backup or snapshot. In this instance, the snapshot is the source volume, and the master is the destination volume during the fast resynchronization.
The slower, but more widely practiced method, is to restore the data from tape.
