This article is from the CD-Recordable FAQ, by Andy McFadden (firstname.lastname@example.org) with numerous contributions by others.
See section (3-20) for commentary. Remember, if you're backing up less
than 650MB of data and don't need fancy features like incremental backups,
you don't *need* special backup software. Just write the files to a CD-R
and put it in a safe place.
For fast, occasional backups of a disk partition or an entire disk, Norton
Ghost is a good way to go for PCs. If you have a second disk or multiple
partitions it can be a useful way to back up your C: drive before installing
something that could muck up your system (like the drivers for a Creative
Labs sound card). If you want full-featured incremental and remote backups,
Veritas Backup Exec is probably a good place to start.
