Abstract: A system for backing up and restoring information includes at least one storage device, a primary server for granting and denying a global lock to devices requesting access to the at least one storage device and at least one secondary server including internal tables for storing information relating to storage in the at least one storage device, the at least one secondary server requesting a global lock from the primary server, wherein after the global lock is granted by the primary server, the at least one secondary server checks its own internal tables to determine whether access to the at least one storage device can be granted.

Abstract: An apparatus comprising a logically contiguous group of at least two drives, a loop and a compression/decompression circuit. Each of the drives comprises (i) a first region configured to store compressed data of a previous drive and (ii) a second region configured to store uncompressed data of the drive. The loop may be connected to the next drive in the logically contiguous group. The compression/decompression circuit may be configured to compress and decompress the data stored on each of the drives.

Abstract: A system and method for ensuring consistency in RAID storage array metadata is disclosed. In one embodiment, the RAID storage array metadata residing in one or more drives is consolidated onto a metadata base volume that is in sync with the current RAID storage array metadata. Further, a point-in-time (PIT) image of the consolidated RAID storage array metadata in the metadata base volume, a system configuration (SC) file, and customer support data (CSD) are obtained. The PIT image, the SC file and CSD can be obtained based on a predetermined time interval and/or upon a change on the RAID storage array metadata. Furthermore, a delta change between two substantially sequentially obtained PIT images, SC files and CSD are determined. In addition, a consistency check (CC) is performed on the RAID storage array metadata based on the determined delta change.
