What exactly shall this be good for?

I immediately thought about ISO files: CD-ROM images. You can do the
very same to any block device:

dd if=/dev/hda1 of=/tmp/disk.bak

Of course, the drive mounted ot /tmp has to be larger than /dev/hda1, in
this case... and it's filesystem should probably support files > 2GB.
Compression might help, too.

Not sure if that's whah you're looking for...
