Partition Image is a fantastic free alternative to the commercial Norton Ghost. Using the KNOPPIX live ISO, I was able to fully back up my Windows hard drive (FAT32), purposely destroy it using deltree, and fully restore it, without a single hitch from the program itself.
If I had to find a fault with the software, I'd have to say it's a little slow backing up/restoring. But that, to be honest is probably not a fault with the program. After all, it was a 2Gb FAT32 partition, and an hour either way to backup/restore the compressed data is a lot easier than having to install Windoze from scratch. The built-in functionality to compress the backup files works like a charm, it compressed those 2Gb's down to about 1.3Gb, easily enough space to fit onto CD.
It took an hour to back up a 10Gb ReiserFS partition on another machine without any compression. And considering the age/speed of the machine, this is totally adequate.
Overall, a fantastic program, and one I'm going to use a lot.
