tar question ...

I bet there is a simple answer to this tar question, but after having RTFM,
I can't figure out a solution. In order to make my backups smaller in
size, I compress the tar image using something like this:
tar cf - [files] | compress -c >/tmp/xxx
cd /tmp; tar c xxx; rm xxx
Unfortunately, this method requires that I maintain enough free disk space to
hold the /tmp/xxx file. What I want to do is pipe the output of compress
directly into tar, avoiding the tmp file altogether. Something like:
tar cf - [files] | compress -c | tar c ...
Anyone know what flags I can use to convince tar that I want it to backup
from standard input?
As an alternative to tar, I've tried piping compress to dd but always get
an error writing to the output device.
I am running Xenix/386 2.3.1 if it matters.
Thanks for any and all help!
