[lug] Tape backup error

[Rob Riggs]

GNU tar can only write to remote tape devices, not files.  See 
http://www.gnu.org/software/tar/manual/html_node/tar_128.html for more 
info.  Note the use of rsh.  You will need to have an rsh server enabled 
on the tape server.  Some of the examples already provided by other BLUG 
member that use SSH instead are better (more secure) choices.

Googling for "GNU tar remote" will provide a lot of hints and howtos.
