  • File array storage architecture having file system distributed across a data processing platform
    Patent number: 6301605
    Abstract: A file array storage architecture comprises a file system that is distributed across a data processing platform consisting of a host computer coupled to an adapter over a high-speed, low latency interface and an input/output subsystem that is located entirely on the adapter. The distributed nature of the architecture enables implementation of the file system in accordance with a modified client-server computing model; that is, the architecture includes a client file system executing on the host computer and a server file system executing on the adapter.
    Type: Grant

  • Mechanism for incremental backup of on-line files
    Patent number: 6101585
    Abstract: A backup mechanism enables incremental backup operations for on-line files of a computer system having an archive bit attribute associated with each file. The mechanism comprises an archive bit change number (ABCN) attribute that is also associated with each file and that is manipulated by a file system of the computer to reflect a correct value of the archive bit when the file is modified during a current backup operation. The ABCN attribute is incremented each time the file is modified to ensure that the file is accurately copied to secondary backup storage during a subsequent incremental backup operation. The mechanism thus enables reliable on-line file modifications which, in turn, substantially increases the efficiency of the computer system.
