ABSTRACT:
Disclosed is a system and method for using a mirrored disk as a bootable backup disk for a computer system. A mirroring routine may be used to create a backup disk, then discontinued during normal operations. Should a problem occur with the main disk, the computer system may be rebooted using the backup disk and the main disk can be rebuilt from the backup disk using the mirroring routine. The system and method may be applied to two disk systems and various multiple-disk arrays such as RAID systems.
