摘要： A deduplication storage system enables new input data to be deduplicated with data of synthetic backups already constructed, and for this purpose efficiently calculates deduplication digests for synthetic backups being constructed, based on already existing digests of data referenced by the synthetic backups. For each input data segment of the plurality of input data segments of a synthetic backup being constructed, a plurality of deduplication digests of stored data segments, referenced by the input data segment, is retrieved from an index. Each input data segment is partitioned into each of a plurality of fixed-sized data sub-segments. A calculation is performed producing a deduplication digest for a data sub-segment, where the calculation is based on the retrieved deduplication digests of the plurality of stored data sub-segments referenced by the input data sub-segment.

摘要： The present disclosure relates to a device and method for storing duplicated data blocks. Specifically, the disclosure proposes a device for eliminating a need for defragmentation in a deduplication backup system. The device is configured to store one or more compressed containers, wherein each container comprises a plurality of segments, wherein one or more duplicated data blocks are stored in the plurality of segments of the one or more containers. The device is further configured to delete a first duplicated data block that is stored in a segment by decompressing the segment, replacing the first duplicated data block with zeros in the segment, and recompressing the segment. In this way, a solution to remove obsolete data which does not require metadata updates, is provided.
