My critical files are on my XP computer. For many years I have used 3rd party backup programs to backup files to an external drive. I also keep a portable drive in our safe deposit box. With all of the 3rd party backup utilities available on the market today, I'm concerned that if I ever had to perform a disaster recovery I might have trouble obtaining a copy of the software I use. My question is - what is wrong with using the universal XP backup program? I guess I really don't know why I opted against it in the first place. It's readily available and appears to do a good job. My only concern would be reconciling the latest version of a file from the full and differential backups in the event of a file restore. I think I'd really like to use the XP backup. Any opinions on this would be greatly appreciated.
