Question on Amiga Forever... I know I could check the docs but since the community is the best DOC out there, I figured I'd try here first

I've had Amiga Forever for a few years now but have not used it other than to root around a bit. I recently dug out my A3000 and want to get back into it classic style. I want to do a fresh install on the hard drive but don't want to lose the software that is on it already.
Can I copy all partitions through Amiga Forever and store them on the PC? What is the easiest way to do so and how long could I expect a 240MB drive to take? I have the required null modem cable ans serisl/usb adapter on the PC.
