APCComm is a program for transfering files between an Amiga and a PC running GNU/Linux using a LapLink cable. It's fast (up to 38 KByte/s), easy to use (no configuration needed) and there is a GUI for the amiga.
fileq transfers files from an incoming queue (directory) to a list of destinations. Destinations can only be directories on remote hosts. The respective transfers are performed using the sftp command line utility from the OpenSSH package.
fsync is a Perl script which allows for file synchronization between remote hosts, containing functionality similar to that of the rsync and CVS packages.
mrsync transfers whole files from one master machine to many remote machines in a LAN using Unix sockets' multicasting capability. It has congestion control so that it won't jam the network traffic relentlessly.
offline files tree mirroring utility allows you to synchronize file trees offline.
GNU OrgaDoc has been designed to easily copy and maitain a pool of documents between computers. You can synchronise your documents pool with rsync or unison. You don't need to install a database server (like MySql or PostgreSql), a HTTP server, a script language (like php, perl, ...)
PFARS is mainly used to sync servers in LVS clusters but also has many other uses. It is based on rsync over SSH and has native support for the Debian package system.
Program Version Syncer
Program Version Syncer checks for updates to programs via ftp or http and downloads them. pvs is smart enough to only download the patches to the programs if they are available.
reclinker is a recursive symlinking utility. It mirrors a hierarchy of files by means of symlinks. It's similar to GNU Stow, but it has no dependencies, is free of forced, confusing package management terminology (like stow dir, target dir, package), and supports both absolute and relative linking, linking into existing hierarchies, and access control for created links and directories. It also has a feature which makes it similar to cpio pass-through mode: it can take a list of files on stdin, and link only those files which occur in the list.
Remosync is a file synchronisation program that can mirror two directories either on the local disk or across a network. It identifies files that have changed by running a CRC check on each file if the CRC's are different then it will copy the file from the source directory to the destination directory.
Remote Filesync is a small tool for synchronizing large files over the net.
rsync-bc is a stripped down version of rsync.
rsynchelper is designed to make it easy for a loose group of mirrors to
quickly and easily setup mirroring time and time again.
rsyncme is a simple implementation of rsync algorithm for efficient file synchronization.
sshync is an auto-sync files or directories over SSH using rsync and fs.watch().
syrep is a generic file repository synchronization tool. It may be used to synchronize large file hierarchies bidirectionally by exchanging patch files. Syrep is truely peer-to-peer, no central servers are involved.
USBSink is a GNOME program for file synchronization over USB. It is designed for users of removable drives, such as flash drives or external hard disks. The goal is to completly automate data transfers after a task has been defined. With file monitoring and hardware detection features, USBSink is able to respond and act according to relevant events across the desktop.
Warsync is a server replication system mainly used to sync servers in LVS clusters but also has many other uses. It is based on rsync over ssh and has native support for the Debian package synchronization.
weex is a utility designed to automate the task of remotely maintaining a web page or other FTP archive. It will synchronize a set of local files to a remote server by performing uploads and remote deletes as required.
wput is a tiny program that looks like wget and does as the name suggests exactly the opposite: It uploads files or recursivly whole directories to a ftp-server and supports resuming.
zsync is a file transfer program. It allows you to download a file from a remote web server, where you have a copy of an older version of the file on your computer already. zsync downloads only the new parts of the file. It uses the same algorithm as rsync.
