Switch device, system, backup method and computer program
Abstract:
A system which includes at least one client, a plurality of file servers, each having a file system, and a switch logically arranged between the client and the plurality of file servers to provide file access services which virtually render the plurality of file systems accessible as a single file system, termed a ‘pseudo file system’, when viewed from the terminal. The switch distributes a command that starts generation of snapshots to the plurality of file servers, which file servers formulate respective snapshots responsive to the command that starts formation of the snapshots. The switch sets the plurality of snapshots, generated by the plurality of file servers, so as to be associated with the file system structure of the virtual file system at the time of formation of the snapshots.
