“Besides the fact that it’s open source, Syncany encrypts the
data on your machine so your files are safe. Further more, Syncany
is extensible through plugins so it will be easy to add new
protocols. Syncany currently supports FTP, Box.net, Amazon S3,
Google Storage, IMAP (example: you could use Gmail or some other
mail service that offers IMAP to sync your files), Local, Picasa
and Rackspace Cloud Files, Windows Share and other protocols will
be added in the future.“Syncany is only available for Linux right now (still unstable)
and comes with Nautilus integration already as well as something
that it’s author describes as “perfect versioning” which allows you
to restore older version of a file, even if the file has been
renamed.”
