yes to both > seems like it should work for the entire drive, > would it work for a single partition if I restore previous partition sizes? yes. A backup of the mbr and the parition table is possible with dd if=/dev/hda of=$FILE bs=512 count=1 > How do I backup my active drive/root partition? do I need a live cd or is it > possible to do from a running system? when the mounted partitions are mounted read only it is reasonably possible. It is possible to do a dd even of a read-write mounted partition, but the probability of a corrupted copied filesystem (i.e. one which does not suvive well to a fsck) is hight (only when there is really NO write activity there is reasonable hope that a fsck will restore the copied filesystem in the wanted state) -- Chi usa software non libero avvelena anche te.
