  • Host-independent incremental backup method, apparatus, and system
    Patent number: 7069402
    Abstract: Block-level operations are tracked within a storage subsystem. Metadata corresponding to the block-level operations are collected within the storage subsystem between snapshot (i.e., backup) instances. The collected metadata are referenced to ensure that only overwritten data blocks are copied to the backup device. The present invention leverages the capabilities of flashcopy operations, frees the host from costly housekeeping tasks, and facilitates efficient backup operations independent of a host or filesystem.
