A distributed file system 102 is used by compute nodes 1113 to access storage devices 1213 via a network 120. A monitor 104 creates events in response to operations, which modify the file system. The events are grouped 106 and sent to backup clients 1313. The backup clients process the events to produce backup requests. The backup clients may use a shared database 150 to co-ordinate the processing. The backup requests are then sent to a backup server 140. Each event group has an identifier and a size. Each event includes the handle of the object in the file system, which is being modified, or the handle of its parent directory. It also includes the event type and the type of object. The events and handles may be Data Management Application Program Interface (DMAPI) events and handles. The file system objects may be file or directory objects. |
