Although this topic came up in the context of a Norton "Ghost"-like
backup strategy, the original poster clearly wanted a way to back
up one disk drive to another.

This is most easily and conveniently achieved by backing up a
32MB partition to another 32MB partition (on another disk, for
best safety).  This makes the "backup" partition an exact copy
of the original, which is bootable (if the original was) and browsable
like any other volume with all standard software.

Backing up to a compressed image is much less convenient in
the event, say, that the original drive fails, so that there is no
place to restore to.  It also is much harder to restore individual
files without special restore software, as opposed to any file
copy program that you like.

In this day of even a _very small_ hard disk being at leasr 240MB,
there is no need or justification for using anything other than a full
partition (volume) backup.
