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.
