backing up before debian install
I am about to install debian on my g4 (alu) powerbook. I would like
to have a dual boot system and if possible, preserve my current OS X
installation. Two questions:
1. is it OK for debian and OS X if I just shrink the OS X partition
using partman, and put an ext3 filesystem partition after it? Or
should I put it before, etc, or the whole thing is not relevant?
2. before using partman, I would like to make a backup of the whole
disk. What tools do you suggest for that?
I can now boot the sarge netinstall cd (current, daily release) and
mount partitions on my firewire/usb2 OWC 250 gb drive. I thought
of making a backup into a file on one of the partitions, using the
tools on the sarge install disk. Is this feasible? What tools
should I use? I thought of dd, but I don't know how could I make
it compare the data it has written with the disk, and I don't know
which device name to use for the whole disk (not just a partition).
If things don't work out, will I be able to restore from this?
Please share suggestions & ideas,
