Fsync is a Perl script which allows for file synchronization between remote hosts, containing functionality similar to that of the rsync and CVS packages. Since fsync is a single Perl script, setting up file synchronization on a new machine is relatively simple. Communication between the hosts is via a socket mechanism, with the remote server started by rsh, by ssh or manually. The program was written with slow modem connections in mind. Fsync supports the concept of merging differences from local/remote hosts with hooks for tools to merge the trees. Fsync requires perl 5.004 or newer. This program is licensed under the GNU Public License.
Release Notes: Added mirroring functionality (so it behaves like rsync). Better support for synchronization between multiple hosts, and more flexible treatment of symlinks is also available. Many other minor changes have been made here.
Release Notes: Now using a different checksum algorithm, which reduces collisions. A per-directory file/directory exclude option means that instead of having to modify the .fsyncrc file, an entry can be placed in the appropriate .fsync-skip file. Symbolic links are now handle better because fsync now works with dangling links. This allows syncing of CFS directories, for instance. Remote error handling is improved.
Release Notes: It now features incremental copying of large files, support for unattended execution, and various bug fixes.
Release Notes: This is the first announcement for fsync.
