It's called Redo Backup and Restore!. It's an OS independent application (in a way) and can be installed into a CD/DVD or USB thus giving you a graphical boot-able environment. It's an advanced "HDD utility" and is actually a more than just another "standard backup tool" because it lets you do things like...
*. Very user friendly GUI.
*. Take partition or entire HDD backups.
*. Perform advanced tasks such as HDD partition resizing, checking for errors, change mount-points, encrypt volumes, benchmark testing, etc.
*. Restore/backup data to local HDD or network drives.
*. Comes with the Firefox web browser (in a Google Chrome type interface, skin actually) by using it you can browse the web (obviously :P) and search for missing drivers or troubleshooting tips for you PC, etc which can be extremely useful.
*. Change the appearance of the GUI (it feels like an entire OS).
*. Comes with few other tools such as a file recover application, file browser (thunar) for manually copying files you want into a CD or a USB, network drive, heck it even comes with a Terminal emulator (which is useful if you want to run a grub-boot-loader related commands from the installed GNU/Linux SO or launching other commands, etc), text file editor, image viewer, etc.
*. Intel/AMD CPU.
*. 512MB of RAM (although you can run it in lower RAM PCs too).
Remember, you can't burn the ISO image directly to a USB drive. First you'll have to make a LiveCD (by burning it into a CD) and then boot-into "Redo" and from the main menu icon choose : "Administration" - "Create Bootable USB" and follow the on-screen instructions.
Seriously!, what else they're missing :D. As said, it's an OS independent utility, although you can make backups or MS Windows and GNU/Linux files systems only (no Mac OSX support, yet, I guess ;-)). You can download the latest version 1.0 from this page.
And finally I'd like to give a big thank you for the developers, it's not just that they've created something excellent and robust but it's completely free and released under the GNU/GPL license too!. So, to everyone who particitaped in creating this amazing utility called Redo Backup & Restore, thank you.
