I too say HD, and if you're hurting for IDE channels, get yourself an IDE controller card to give you four more - less than $40, and superior speed. If you have to take it offsite, it's still not that big a hassle to pull an internal drive out of the box and swap it with another once a week or whatever. I use Ghost and will never boot from another floppy if I can help it. I produced a CDR that is bootable and has Ghost.exe on it (very easily done - see the manual), and I can boot from that CDR and be in Ghost a ton faster than it takes to even boot Win2000. Ghost runs 5 times as fast from the CDR than it runs from the floppy, too. Make sure you have mouse support in Ghost, too, not a problem. To make things even more convenient, write yourself some batch files that automate your backup scenarios. I'm going to do that, and probably also run those from CDR or CDRW's. It won't launch the Ghost GUI from the autoexec.bat (as I'm doing now) but will either run my Ghost backup (not the GUI but the backup process itself) from autoexec.bat, run another batch file from autoexec.bat or just send me to a command line where I can run whatever batch file I want, either from the CDR or from one of my HDs. That way, you don't have to go through all the motions in the Ghost GUI, which is wasted motion if you are just doing the same backup over and over again. It also eliminates the possibility of making a careless mistake, which could be very costly. Making your Ghost batch files is also all in the manual Ghost manual. I'm running Ghost 2001.
