  • Patent number: 5873103
    Abstract: The data storage management system provides the capability to move and/or copy the placeholder files from one file server volume to another file server volume, even if the destination file server volume resides on a different file server. This is accomplished by the use of unique and immutable migration keys which are included in the placeholder entries to identify the location of the associated data file with absolute certainty. In addition, a duplicate copy of the placeholder catalog file is maintained in the system to prevent loss of file system integrity in the event that the active placeholder catalog file is corrupted. This placeholder data is maintained in a placeholder volume catalog which provides users with a file-system-like view of the placeholder files which reside on the selected volume.

  • Patent number: 5832522
    Abstract: The data storage system is connected to a local area network and includes a storage server that on a demand basis and/or on a periodically scheduled basis audits the activity on each volume of each data storage device that is connected to the network. Low priority data files are migrated via the network and the storage server to backend data storage media, and the directory resident in the data storage device is updated with a placeholder entry to indicate that this data file has been migrated to backend storage. When the processor requests this data file, the placeholder entry enables the storage server to recall the requested data file to the data storage device from which it originated.
