  • Patent number: 11055005
    Abstract: Techniques are provided for background deduplication using trusted fingerprints. Trusted fingerprints of blocks are inserted into a trusted fingerprint store as the blocks are being allocated by a file system sequentially according to block numbers of the blocks. In this way, the trusted fingerprint store is indexed by block numbers of where the blocks are stored. Blocks that are to be deduplicated are identifying by sorting the blocks based upon weak fingerprints, and moving duplicates to a dup file. The dup file is sorted based upon block numbers. Trusted fingerprints are loaded from the trusted fingerprint store for deduplicating the blocks within the dup file.

  • Patent number: 10838643
    Abstract: A technique for managing cache in a storage system that supports data deduplication renders each of a set of data blocks as multiple sub-blocks and loads a cache-resident digest database on a per-block basis, selectively creating new digest entries in the database for all sub-blocks in a block, but only for blocks that contain no duplicate sub-blocks. Sub-blocks of blocks containing duplicates are excluded. By limiting digest entries to sub-blocks of blocks that contain no duplicates, the storage system limits the size of the digest database, and thus of the cache, while also biasing the contents of the digest database toward entries that are likely to produce deduplication matches in the future.

  • Patent number: 10795869
    Abstract: Techniques and solutions are described for facilitating data archival, including for improving compliance with retention policies and legal requirements. Data objects can be assigned an expiration date based on properties of the data objects and rules associated with such properties. The data objects can be stored in an archive. In some cases, the data objects can be automatically deleted when the expiration date passes. In other cases, the data objects can be manually deleted when the expiration date passes, with deletion not occurring, and an error being generated, if the expiration date has not passed. Unstructured data objects can be associated with structured data objects through association lists, where an association list can be used to delete such unstructured data objects with or without deletion of an associated structured data object, and where the unstructured data objects can be linked with retention policy information of the structured data object.

  • Patent number: 10783047
    Abstract: Provided are a computer program product, system, and method for forming a consistency group comprised of volumes maintained by one or more storage controllers. At least one storage controller is caused to perform reservation operations for point-in-time copies of storage units to allocate storage resources and a data structure for a point-in-time copy. Upon successfully completing the reservation operations for all the point-in-time copies, Input/Output (I/O) operations to the storage units of the point-in-time copies are suspended. If I/O operations were successfully suspended at the storage units for all of the point-in-time copies, then suspension of I/O operations is ended I/O operations are allowed to continue at the storage units of the point-in-time copies. The point-in-time copies at the storage units are formed at which the suspension of I/O operations was ended after being successfully suspended. The point-in-time copies are consistent as of a same point-in-time.

  • Patent number: 10761943
    Abstract: A method for backing up data is disclosed. In one embodiment, such a method includes identifying a volume of data to back up, and determining a number of backup tasks that can operate in parallel to back up data in the volume. The number of backup tasks may be based on an amount of memory available, a fragmentation level of a target storage area, a number of tape mounts that are available, or the like. The method then divides the volume into a number of sections corresponding to the number of backup tasks. Each section is associated with a particular backup task. The method then initiates the backup tasks to back up their corresponding sections in parallel. In certain embodiments, each backup task generates a data set storing backup data from its corresponding section. A corresponding system and computer program product are also disclosed.
