Making backups of important folders should become a routine for everyone, simple as that. Back up to another internal drive, back up to a flash disk, back up to an external drive, or back up to an remote source, it doesn’t really matter as long as you make the effort to backup on a regular basis.
Linux users will be familiar with the powerful rsync command line file and directory synchronization tool, but if you are an Ubuntu user then chances are you’re not particularly keen on messing about on the command line. So enter a great little alternative called Grsync, which is basically a graphic user interface for rsync!
In a nutshell, Grsync allows you to synchronize folders, files and make backups, while utilizing the power of the tried and tested rsync in the background to do the actual heavy lifting.
It costs nothing and is opensource. It can be effectively used to synchronize local directories and it supports remote targets as well (even though it doesn’t support browsing the remote folder). Grsync is available on fair number of Linux flavors (like Ubuntu), Windows and Mac OS X.
Note that you do need the rsync command line tool installed on your system in order for Grsync to work, but don’t fret too much about that as nowadays most distros come with it preinstalled.
