But there are certainly simple yet powerful tools that can be found according to your needs if you know where to look :). In that sense if you were looking for an easy to use, excellent data backup/restore tool for GNU/Linux, then DejaDup is a really good one.
It's part of the Gnome desktop and inherits the simplicity thus if you're GNU/Linux sever administrator who's quite familiar with having lots of options, etc then at first you might be a bit disappointed, but the rest assured, DejaDup is certainly a powerful tool nonetheless.
*. It supports two main types of backup methods - remote (FTP, Windows share, etc) and local data backups (from partition to partition for example) + the current trend of syncing files into a data Cloud as well.
*. For Cloud data backups, it currently supports - Amazon S3 and Racksplace cloud services at the moment.
*. Encrypt (can be disabled) the backup data.
*. Incremental backup support.
*. Ability to automatically add/avoid certain folders (such as Trash, etc).
*. Schedule and change how long the backup files should be stored (forever, month, etc).
*. Restoring ability (obviously :D).
Well, that's about it!. You can install Deja-Dup in Ubuntu 11.04 Natty Narwhal by issuing the below command in your Terminal.
sudo apt-get install deja-dupOnce installed, just click on the backup button or the restore (the only two buttons on the GUI, written in GTK+) and follow the on screen guidelines.
But, after installing if it doesn't show up in the menu, then press "Alt" + "F2" and enter "deja-dup" and press "Enter". That should do the trick. Good luck.
