- compression is really best used if there's some transfer across a network
- involved, eg.
-
- host0# rsh host1 "cd /dir0; tar cf - dir | compress" | \
- rsh host2 "cd /dir1; uncompress | tar xpfB -"
-
- which copies directory host1:/dir0/dir to host2:/dir1/dir from a trusted host host0
-
- the compression can substantially reduce the elepsed time of the transfer
