    摘要: A method to sequentially deduplicate data, wherein the method receives a plurality of computer files, wherein each of the plurality of computer files comprises a label comprising a file name, a file type, a version number, and file size, and stores that plurality of computer files in a deduplication queue. The method then identifies a subset of the plurality of computer files, wherein each file of the subset comprises the same file name but a different version number, and wherein the subset comprises a maximum count of version numbers, and wherein the subset comprises a portion of the plurality of computer files. The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue.

    摘要: A method to select a deduplication protocol for a data storage library comprising a plurality of data storage devices configured as a RAID array, by establishing a normal deduplication protocol, a RAID failure deduplication protocol, and a multiple storage device failure deduplication protocol. The method receives host data comprising a plurality of interleaved data blocks. If the system is operating without any storage device failures, then the method processes the host data using the normal deduplication protocol. If the system is operating with a storage device failure, then the method processes the host data using the RAID failure deduplication protocol. If the system is operating with multiple storage device failures, then the method processes the host data using the multiple storage device failure deduplication protocol.

The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue. During the deduplicating, the method receives new computer files comprising the same file name, stores those new computer files to the deduplication queue, but does not add those new computer files to the subset.
