I just wanted to do backup of some machines (Linux & FreeBSD mixed
env.). Every machine has DVD burner and directory that is bigger than
media size (>4GB). I thought about some universal solution for both OSs.
I found project called cdbackup, but it is only avaliable for Linux.
Combined with star I think it should be enough for my needs.
