I have a system that has a dual boot of windows xp and redhat 8.0. I was wondering what the best way to back up this system would be? Could I just use Ghost, or would that cause problems with the different file systems? I would appreciate any advice anyone can give me. Thanks.

I prefer doing system backups with dump. Like that:

dump -0 -z9 -f root.dump /

I've stored the images at a internal FTP server. If for instance server a's HDD died I just put in Knoppix CD, reboot and get the images from the FTP server and then create the partitions and restore. That's easy and saves a lot of time ...

You can't use dump for a all-the-time backup though. Like I created a image once the systems were set up completely and then creating checksums on the dumps (to verify integrity). Now I backup just variable files (configuration files, logs, etc) using tar.
