The new filesync feature ensures that data is moved automatically between the portable computer and the server. filesync is primarily intended for use on nomadic systems, although it may also be useful for backup and file replication on more permanently connected systems. Its purpose is to keep copies of files in sync between multiple systems, typically a server and a portable computer.
filesync can be used to maintain lists of files and directories to be kept in sync between multiple systems. Each time it is invoked, it examines all the files on both systems, determines which files have changed, and propagates the changes (creations, deletions, edits). It can deal with changes in both directions, and with conflicting changes.
