"With an incredibly simple user interface and the ability to
encrypt and backup your data to network drives, external drives,
FTP/SSH servers and even Amazon S3 storage, Déjà Dup
is the perfect Linux backup solution. Set up a secure,
regularly-scheduled backup in minutes. It's like Carbonite for
Linux, except you can pick where your data goes.
"Linux backup software is certainly nothing new. Many people
swear by rsync for their backup needs, while others like Back In
Time, an easy backup program for Linux.
"Those applications might work for you, but Déjà
Dup will for sure. Aiming to allow you to do backups the right way
– that is, to quote their web site, "encrypted, off-site, and
regular" – this program is based on command-line utility
duplicity but sports a GUI anyone can use."
