  • Dynamic network access of snapshotted versions of a clustered file system
    Patent number: 9436693
    Abstract: The various embodiments are directed towards enabling access to snapshotted versions of files in a distributed file system. The distributed file system may receive a file system operation request that includes at least an entry-ID and a snapshot-ID. File system operation requests may include operations such as reads, writes, moves, or the like. Directory entries that match the entry-ID and the snapshot-ID may be looked up and retrieved from the distributed file system. The retrieved directory entries may also be arranged to include a generation-ID. In the directory entry matching the snapshot-ID, if the generation-ID and the snapshot-ID are different, another directory entry may be looked up from the distributed file system using the entry-ID and the generation-ID. Then the initially requested file system operation may be performed on the retrieved directory entry.
