  • Patent number: 8793226
    Abstract: The present invention provides a system and method for estimating duplicate data in a storage system. A duplicate estimation application executes on a client of a storage system selects an element from an intended destination such as, e.g., a data store of the storage system. If the element is a file (or other data container), the application reads data from the file and computes a fingerprint of the read data. The computed fingerprint is then logged in a fingerprint database, which is illustratively stored on a storage device connected to the client executing the application. This process repeats until the entire file (or other data container) has been read and fingerprinted. Once all elements have been scanned, fingerprinted and recorded, the application identifies any unique entries within the fingerprint database. Utilizing this information, the application computes an estimated space savings that may be realized by employing a data de-duplication technique.

  • Patent number: 8793223
    Abstract: A network storage server includes a tool for detecting and fixing errors while the network storage server remains online (available for servicing client requests), which includes enabling a user to approve or disapprove remedial changes before the changes are committed. The technique bypasses the usual consistency point process for new or modified data blocks representing potential remedial changes. At a consistency point, dirty data blocks representing the potential remedial changes are written to a change log file residing outside the volume. The modified data blocks are written in sequential order to logical blocks of the change log file. In response to a user input indicating that a potential change should be committed, the corresponding modified data blocks are read from the change log file in the order in which they were written to the change log file, and they are written to persistent storage in that order.
