Best backup tools in Linux.

Data lose is one of the major fears of the users.Disk failures & accidents are the common cause of data lose which can occur at any time, so it's really important to keep track of our data regularly.
Backup tools comes with various features:
-enable you to identify important files and directories that are then constantly monitored and regularly backed up.
-perform incremental backups, which – after making a complete initial imprint of the directory – will then only make copies of new files or those that have changed since the last backup inorder to tackle redundancy.
-compress your data so you can store it more efficiently.
-tools that will encrypt your data when making copies.
-GUI and command line flavours

Some of the well known Linux Backup tools are:
Pybackpack
A vailable in most software repositories, Pybackpack is designed to be a friendly backup tool, and is notable for being easy to install manually thanks to its bundled Python installer script.
Rating: 7
Fwbackups
With Fwbackups, you can either perform on-demand backups or create sets and task Cron with automatically backing up your data. All this is conveniently offered from a slick graphical interface.

Déjà Dup
Duplicity, the command line gem that offers such features as remote backups and encrypted incremental archives, is just too exhaustive to cover here. Still, we've managed to find the best graphical front-end to Duplicity around: the brilliant Déjà Dup.

Backerupper
Although not available in the software repositories of any big-league distributions yet, Backerupper is still popular having received extensive blogosphere coverage. The tarball contains an install.sh script if you wish to install Backerupper to disk, but it works just as well without installation. Simply double-click the backer executable file.

Simple Backup Suite
The Simple Backup Suite, or Sbackup, is a set of Python scripts that provide two graphical interfaces: simple-backupconfig and simple-restore-gnome. Don't panic if it isn't part of your distro's repository – with its tiny dependency list, it's easy to install, even from source.

Back In Time
Originally intended as a replacement for scp and the rcp tools, rsync is now often used for performing backups. There are many graphical tools that use it and Back In Time is just one.
Rating:7
LuckyBackup crams almost all the features of the tools we've covered so far into a single package, while trying to keep its interface clean and simple. Great tooltips and a comprehensive user manual help you to make sense of all that's on offer here.
Rating:7
Keep
Just like rsync, rdiff-backup is a command line utility to back up a directory to another location, even over a network. It's also similar to rsync in that it has inspired many graphical front-ends, and Keep is our weapon of choice for KDE.
