ABSTRACT:
In a client/server environment having a backup subsystem, a method and means for reducing the storage requirement in said backup subsystem and further reducing the load on the transmission bandwidth between the clients and the backup subsystem. This is accomplished by maintaining a copy of frequently accessed files on both the server and clients when a file is modified on the client, a delta file which is the difference between the base file and the modified version of the base file is created and transmitted to the server to be stored on a storage medium which is part of the backup subsystem. Alternatively, whenever a client modifies a file, the base version of that file is transmitted to the client from the server, a delta file is created and transmitted to the server to be stored on the storage device which is part of the backup subsystem. Alternatively, modified files are transmitted to the backup server and the differencing is carried out at the backup server.
