摘要： Techniques herein are for sharing data structures. In embodiments, a computer obtains a directed object graph (DOG) containing objects and pointers interconnecting the objects. Each object pointer (OP) resides in a source object and comprises a memory address (MA) of a target object (TO). An original address space (OAS) contains the MA of the TO. The objects are not contiguous within the OAS. The DOG resides in original memory segment(s). The computer obtains an additional memory segment (AMS) beginning at a base address. The computer records the base address within the AMS. For each object in the DOG, the computer copies the object into the AMS at a respective address. For each OP in the DOG having the object as the TO of the MA of the OP, the computer replaces the MA of the OP with the respective address. AMS contents are provided in another address space.

摘要： For a data copying operation, data compression using constant number-of-track-groups and a thinly provisioned target device facilitates incremental updates where the size of the compressed data on the target device changes. Compressed data is written to the same LBA as the beginning of the source device chunk cluster LBA (1:1 mapping of data start). A termination string or other demarking device is used to identify space freed on the target device resulting from compression. During an incremental update only changed chunk clusters are changed, and freed space is changed accordingly if necessary.

摘要： An information management system provides a data deduplication system that uses a primary table, a deduplication chunk table, and a chunk integrity table to ensure that a referenced deduplicated data block is only verified once during the data verification of a backup or other replication operation. The data deduplication system may reduce the computational and storage overhead associated with traditional data verification processes. The primary table, the deduplication chunk table, and the chunk integrity table, all of which are stored in a deduplication database, can also ensure synchronization between the deduplication database and secondary storage devices.

摘要： Techniques herein are for sharing data structures between processes. A method involves obtaining a current memory segment that begins at a current base address within a current address space. The current memory segment comprises a directed object graph and a base pointer. The graph comprises object pointers and objects. For each particular object, determine whether a different memory segment contains an equivalent object that is equivalent to the particular object. If the equivalent object exists, for each object pointer having the particular object as its target object, replace the memory address of the object pointer with a memory address of the equivalent object that does not reside in the current memory segment. Otherwise, for each object pointer having the particular object as its target object, increment the memory address of the object pointer by an amount that is a difference between the current base address and the original base address.

摘要： A method for storing data in a data storage system by partitioning the data into a plurality of data chunks and generating representative data for each of the plurality of chunks by applying a predetermined algorithm to each chunk of the plurality of chunks. Subsequently, the representative data is compared and sorted. Representative data for base data chunks and representative data for other data chunks that can be stored relative to the base data chunks are identified by evaluating the sorted set of representative data. Finally, each of the other data chunks identified as those that can be stored relative to a base data chunk are stored in the data storage system as the difference between the data chunk and a base data chunk.

摘要： It is provided a computer system, comprising a server and first and second storage systems. The first storage system stores deduplicated data sharing at least a part of data with other data, shared data shared by a plurality of pieces of the deduplicated data, and first type data representing a type of the stored data including the deduplicated data and the shared data. The deduplicated data is associated with the shared data by a pointer to the shared data, and includes differential data indicating a difference from the shared data. The server creates second type data representing a type of the data stored in the second storage system from the first type data. The second storage system stores the shared data associated with the deduplicate data at a reading position before a position at which the deduplicated data is read in sequential reading and stores the second type data.

摘要： Techniques are provided for de-duplication of data. In one embodiment, a system comprises de-duplication logic that is coupled to a de-duplication repository. The de-duplication logic is operable to receive, from a client device over a network, a request to store a file in the de-duplicated repository using a single storage encoding. The request includes a file identifier and a set of signatures that identify a set of chunks from the file. The de-duplication logic determines whether any chunks in the set are missing from the de-duplicated repository and requests the missing chunks from the client device. Then, for each missing chunk, the de-duplication logic stores in the de-duplicated repository that chunk and a signature representing that chunk. The de-duplication logic also stores, in the de-duplicated repository, a file entry that represents the file and that associates the set of signatures with the file identifier.

摘要： A cooperative data file coloring backup system includes a file color agent (FCA) and a file color storage cloud controller (FCSCC). The FCA assigns a color to a data file. The assigned color is associated with a highest projected data reduction factor achieved when backing up the data file from a host to one of various storage devices comprised within a data backup storage area network. The FCSCC maintains a list of file types and associated data reduction factors that are achieved during a backup of the file types and provides to the FCA a storage path from the host to a particular storage device within the storage area network associated with the highest data reduction factor and file type. The FCA may implement the storage path based upon the assigned color for each backup request received by the host.
