Methods and systems for preventing unnecessary file transfers between a server and a remote node

摘要

Unnecessary file transfers between a data processing server (104) and a plurality of remote/mobile nodes (116) which are temporarily and intermittently linked to the server are prevented if insufficient storage is available at the destination or if an updated version of an existing file is not newer than the existing file. File transfers are inhibited if insufficient storage space is available by checking the disk space or other storage space at the destination and inhibiting file transfer if insufficient space is available. Transfer of an updated version of a file is prevented if the updated timestamp is not newer than the existing timestamp at the destination. Unnecessary file transfers are thereby prevented and connection time of the remote/mobile link is reduced.
