Heh, just shot down another suggestion on #utah a bit ago. Man, I'm
going to have to write this on correctly soon. But still too lazy to do
so. The previously suggested find -exec will work, albeit a bit slowly.

The example you show is dangerous. xargs may have to run the command
more than once, whacking the partially completely backup. Safer would be
to stop doing a one liner.

echo > backup.tar
find | xargs tar

Of course, the problem won't show up until your backup is large enough
to make discovering the problem more potentially disastrous.
