Redo Backup and Recovery

Redo Backup and Recovery is an imaging backup tool with a difference. Instead of installing a program, you download a large (249MB) ISO file, and burn it to CD or USB key drive. Then just boot from it to launch a simple tool which can back up your drives, and restore them later (even if Windows won't start).

There's also an undelete tool, and even a web browser if you need to look for help on your PC problems.

The program isn't exactly convenient, then. You can't schedule backups, they all have to be run manually, and there are very few options.

But it's also easy to use and free for everyone, so if you only want to run backups occasionally - or want a system you can use on any PC, without installing software - then it might be worth a look.
