Where I work, we've been lacking a DLT drive for a while.  I ran into
this problem when trying to continue to do backups.  I ended up making
tarballs on a directory-by-directory basis since I couldn't fit a whole
directory tree into one big file.  OTOH, this makes it a little faster
to get what you want, rather than waiting for tar to seek through many
gigabytes of stuff.

Interestingly, I found out that tar.gz-ing the files could allow us to
store five backups on a single 30GB tape (we have a lot of inefficiently
stored databases -- usually flat text files -- laying around).  I
suppose that doing tar.bz2 could bring that up to six.
