  • Method and system for encrypting data
    Patent number: 9742564
    Abstract: A processing device may generate a data encryption key configured to encrypt unique data within a clone of an encrypted data set and associated with a set of transaction identifiers of a transaction based file system. The processing device may further wrap the data encryption key with a wrapping key, create a cloned encrypted data set with the data encryption key, and store the wrapped data encryption key with the cloned encrypted data set indexed by at least one of the set of transaction identifiers.
    Type: Grant

  • Dynamic intent log
    Patent number: 7606812
    Abstract: A method for dynamic intent logging in a file system. The method including pre-allocating a first log block, receiving a request to write a first set of deltas into a dynamic intent log, determining whether a size of the first set of deltas is larger than a size of the first log block, if the size of the first set of deltas is not larger than the size of the first log block, storing the first set of deltas in the first log block and pre-allocating a second log block.

  • Automatic intent log testing
    Patent number: 7490096
    Abstract: A method for testing an intent log for a file system that includes creating a first file system, issuing a command to freeze the first file system, performing a plurality of commands on the first file system to obtain a plurality of deltas, wherein each of the plurality of deltas is stored in the intent log and is not committed to the first file system, copying the first file system to obtain a second file system, committing each of the plurality of deltas in the intent log to the second file system, unfreezing the first file system and committing each of the deltas in the intent log to the first file system, and comparing the first file system, after committing each of the deltas in the intent log, to the second file system to determine whether the intent log is valid.
