<P>PROBLEM TO BE SOLVED: To provide efficient block level incremental snapshots of primary storage devices, and instant availability of such snapshots in an immediately mountable form that can be directly used in place of the primary storage device. <P>SOLUTION: Related systems and applications includes: an enterprise image destination for backup images; a mirroring technique creating a replacement physical primary facility while working with a second storage unit as the primary source file system; and a technique for eliminating redundant data in backup images when multiple systems with partially common contents (e.g., operating system files, common databases, application executables, etc.) are being backed up. <P>COPYRIGHT: (C)2013,JPO&INPIT |
