A compressed disk image that can be mounted via mount -o loop file?
I have a handful of hard drives I want to back up before I re-purpose them. I would really like to use some kind of compression (preferably xz or gzip), but I want it in a way where I can just mount it on the command line without extracting it first. Is this possible?

I know this: http://e2compr.sourceforge.net/ I have not tested it and need kernel patching. There are more option if you only want read-only support (see the link Related Software on the last page).

Oh yeah, if all you need is read-only, squashfs is brilliant. Compress with xz, it'll shrink almost down to 30% of the original size.
