(Typically the server is the source system and the nomadic system is the destination.) Access to the server file tree is via NFS mount on the client, typically managed via the automounter. (Contrast this to the rsync command [see rsync in the earlier section "Alphabetical Summary of Common Commands"], where the name of the remote host is provided explicitly.)

Users may edit this file with any text editor in order to adjust filesync's operation. The file $HOME/.filesync-base keeps track of which files are subject to synchronization, and their states when last synchronized. Users should not edit this file.
