摘要： Chunks that commonly occur in each content type are aggregated in a first container. To be more specific, a storage device used for content backup is configured with: (1) a memory device that provides a memory region for one or a plurality of first containers used to store first chunks that commonly occur in each content type among chunks extracted from the contents of writing targets, and for one or a plurality of second containers used to store other chunks than the first chunks; and (2) a backup unit that decides whether each of the chunks extracted from the contents of the writing targets is a first duplication chunk duplicating a chunk stored in the first container, and further decides, for only a chunk that is decided not to be the first duplication chunk, whether each of the chunks is a second duplication chunk duplicating a chunk stored in the second container, and then stores only a chunk that is decided not to be the second duplication chunk in the second container.

摘要： The present invention not only reduces the load but also enhances the accuracy of de-duplication in a storage apparatus which performs in-line de-duplication processing and post-process de-duplication processing. A storage apparatus comprises a storage device and a controller. The controller receives multiple files, and by performing in-line de-duplication processing under a prescribed condition, detects from among the multiple files a file which is duplicated with a file received in the past, stores in the temporary storage area a file other than the detected file of the multiple files, and partitions the stored file into multiple chunks, and by performing post-process de-duplication processing, detects from among the multiple chunks a chunk which is duplicated with a chunk received in the past, and stores in the transfer-destination storage area a chunk other than the detected chunk of the multiple chunks.

摘要： A cache memory is utilized effectively because data redundancy elimination is executed. A controller manages the cache memory by dividing it into a first area and a second area. When receiving a write access request from an access requestor, the controller divides a data block, which is an access target, into a plurality of chunks and searches the first area first and then the storage apparatus based on each chunk. If chunk storage information, indicating that each chunk is stored in the storage apparatus, does not exist in the first area or the storage apparatus, the controller executes chunk storage processing and creates and stores the chunk storage information. If the chunk storage information exists, the controller eliminates the chunk storage processing for storing the chunks. If the chunk storage information does not exist in the first area, the controller stages the chunk storage information from the storage apparatus to the first area on condition that the first area has an unused area.

摘要： A data management system and data management method capable of inhibiting an increase of I/Os caused by deduplication are provided.Data blocks are managed by grouping them; a plurality of chunks belonging to the same group after deduplication are collectively managed as a chunk data set; and if a host system issues a data block deletion request, garbage collection of the relevant chunk data set is performed based on the number of times of references of the chunk data set and the chunk data set after the garbage collection is managed by overwriting the existing chunk data set with a new chunk data set composed of only chunks of data blocks which are not deleted.

摘要： A data management system respectively computes first hash values while sliding a window a prescribed amount at a time with respect to a prescribed range from a start location of a data block to a prescribed size. The system extracts, from among the first hash values, a first hash value, which is equivalent to a characteristic value, and partitions the data block into a first chunk of data at a location corresponding to this first hash value. The system determines coincidence between a first chunk of data and a stored second chunk of data, and prevents duplicate data from being stored twice.
