#  Slick script heavily stuffed with and possible stuffed up (things deleted) by 
#  Lachlan M. D. Cranswick 22nd April 1999 - l.cranswick@dl.ac.uk
#  http://www.ccp14.ac.uk - Daresbury Laboratory, Cheshire, UK.
#  Result is not so slick but seems to do the job as wanted - Lachlan.
#  TAPE=/dev/tape links to /dev/rmt/tps1d5 
#  TAPE=/dev/rmt/tps1d5 is telling the Seagate Scorpion 24 DLT/DDS3 to NOT do compression.
#  TAPE=/dev/rmt/tps1d5c is telling the Seagate Scorpion 24 DLT/DDS3 to do compression.
#  Last mod 23rd April 1999 - clean things up for cron.
#  Last mod 24th April 1999 - changing things so it will fit on one disk (forget saving / )
#  1st June 1999 Do a very simple script as this is for a very simple system.
#                - Also have good indication that tape drive is not compressing as it should.
# Level 1 script modified from level_0 script 9th June 1999
# Hopefully final Spiv up with logs and stuff 22nd June 1999 - Lachlan Cranswick
# In the level one backups - put touch commands on the important files so that these files
#  always retrievable from any level one backup.  24th June 1999
#  (though could be highly stupid thing to do?) Lachlan
