Only if you don't care about the data you are backing up.  The danger of
a compressed backup is that one small error on the tape and you lose all
the files from that point on.  A safer method is to compress the individual
files before backing them up.  The program afio has a flag to do this for
you so that you don't have to compress them on disk first, problematical
at best for a full backup.
