Patent Images
1. A system for restoring data from backup storage using a mirror disk and a primary disk, the restored data being restored to the primary disk which is accessible by a database application in a host system, the system comprising:
- a reflector to copy pre-restored data from the primary disk to the mirror disk in response to a restore request; and
a primary disk restorer to restore data from a backup storage device to the primary disk, independent of the mirror disk, after the pre-restored data is copied from the primary disk to the mirror disk.

Abstract
When performing mirrored disk restores, including both disk level mirrored restores and file level mirrored restores, rather than first restore data to a mirror disk and later move that data to the primary disk, the data on the primary disk is first copied to the mirror disk, and thereafter, the data is restored from the backup storage device to the primary disk, independent of the mirror disk.
