I also recommend using a second hard drive for backup (either in a mobile tray or external, USB2 or FW, enclosure) - most other reasonably priced media are just too small and/or too slow any more. Remember: "The only backup that will do you any good is the one that actually gets done." Anything that slows the process (like having to change media) increases the likelihood that backups won't get done..
. Programs like Ghost/DriveImage/TrueImage - are (obviously) drive imaging programs. Their image files are fragile in the fact that a one or two byte error can lose you either all your data or at least whatever data lies beyond the error in the file. Not suitable for secure backup - but fine for getting back up quickly when severe crashes occur - as long as the image file(s) is(are) intact. The ideal would be to use image software plus the following...
. For secure backup you should use a file-by-file method (such as Windows backup) with 'compare after write' feature. One program that seems to be in current favor for Win is Retrospect. And NTI's program (forget the name) can do both f-b-f and image types. The nice thing about f-b-f is that you can restore just the files you need and not have to restore the whole image...
. One of the trade magazine web sites has a current article on external, hard drive based backup systems and as a sidebar it has an article on some of the current softwares (I wonder why My Backup (successor to Backup Exec) is missing - has it died already?). I think it was on
PCMAG.com . Of course, as an AT denizen, you know that you can build a USB/FW external drive (easily equal to any of those included in the tests) for much less than the prices listed in the article.
There are also several good Shareware backup programs that are quite good and inexpensive. Check
http://www.majorgeeks.com or other shareware archive. Make sure whatever backup you choose has "Crash Protection" - which means it can recover even when you can't boot your main operating system. IOW, when you have to start from scratch with FDISK/Format, etc... IMO, anything less is worthless!!!

Dont forget, you want to do regular Scandisks (with full surface test enabled) on your backup drive just as you do your internal drives. No sense backing up to a drive that is going TU...
