Abstract: A method and apparatus for retention of active data stored in memory using multiple indexing systems for data storage. An embodiment of a method for retention of active data in a storage server includes reading data into a first location of a main memory of the storage server. The data in the first location indexes data elements in a long-term data storage in a first manner. The method further provides for copying the data from the first location into a second location in the main memory of the storage server, where the data in the second location indexing the data elements in the long-term data storage in a second manner.

Abstract: Overwriting part of compressed data without decompressing on-disk compressed data is implemented by receiving a write request for a block of data in a compression group from a client, wherein the compression group comprises a group of data blocks that is compressed, wherein the block of data is uncompressed. The storage server partially overwrites the compression group, wherein the compression group remains compressed while the partial overwriting is performed. The storage server determines whether the partially overwritten compression group including the uncompressed block of data should be compressed. The storage server defers compression of the partially overwritten compression group if the partially overwritten compression group should not be compressed. The storage server compresses the partially overwritten compression group if the partially overwritten compression group should be compressed.

Abstract: A method and system for eliminating the redundant allocation and deallocation of special data on disk, wherein the redundant allocation and deallocation of special data on disk is eliminated by providing an innovate technique for specially allocating special data of a storage system. Specially allocated data is data that is pre-allocated on disk and stored in memory of the storage system. “Special data” may include any pre-decided data, one or more portions of data that exceed a pre-defined sharing threshold, and/or one or more portions of data that have been identified by a user as special. For example, in some embodiments, a zero-filled data block is specially allocated by a storage system. As another example, in some embodiments, a data block whose contents correspond to a particular type document header is specially allocated.

Abstract: A data set on a physical storage device is associated with an active bitmap and a persistent point-in-time image (PPI) exclusion bitmap, where each bit in the bitmaps is associated with a data block in the data set. The active bitmap and the PPI exclusion bitmap are used to determine which of the data blocks in the data set are to be included in a PPI of the data set.

Abstract: A request is received to remove duplicate data. A log data container associated with a storage volume in a storage server is accessed. The log data container includes a plurality of entries. Each entry is identified by an extent identifier in a data structures stored in a volume associated with the storage server. For each entry in the log data container, a determination is made if the entry matches another entry in the log data container. If the entry matches another entry in the log data container, a determination is made of a donor extent and a recipient extent. If an external reference count associated with the recipient extent equals a first predetermined value, block sharing is performed for the donor extent and the recipient extent. A determination is made if the reference count of the donor extent equals a second predetermined value. If the reference count of the donor extent equals the second predetermined value, the donor extent is freed.
