  • Method and system for allocating multiple attribute storage properties to selected data storage resources
    Patent number: 7599905
    Abstract: A method of attribute based resource allocation is presented. A resource such as a pool of storage has certain properties or attributes associated with portions of the pool. When a request for storage is needed, the requester provides a selection expression which comprises properties and logical operators. From the selection expression a determination is made to allocate portions of the storage pool which meet the requirements of the selection expression.

  • Method and apparatus for computing file storage elements for backup and restore
    Patent number: 7516288
    Abstract: A method and apparatus for method for transferring files between a primary storage system and a backup and restore system is described. The system generates collapsed extents which are used to specify data to be backed up to a backup and restore system. The backup and restore system backs up data based on the collapsed extents but records all extents included in the collapsed extents to enable the system to facilitate restoration of the data at a later point in time.

  • System and method for backing up data stored in multiple mirrors on a mass storage subsystem under control of a backup server
    Patent number: 6611923
    Abstract: A backup server controls the backing up of data stored on a mass storage subsystem in response to a backup request from a host identifying data to be backed up during a backup operation, the mass storage subsystem storing data in a plurality of mirrored copies. The backup server comprises a discovery module, a preparation module, an execution module and a clean-up module. The discovery module receives the backup request and identifies, during a discovery phase, at least one storage location on the mass storage subsystem on which data to be backed up during the backup operation is stored. The preparation module, during a preparation phase following the discovery phase, enables the mass storage subsystem to sever one of said mirrored copies and make it available to backup server for the backup operation.
