# Description Backs up important files to tape. #
# Written On 09/06/01 #
# Modifications 09/15/01 - Added /var to backup directory list. Also added the #
# ability to calculate tape usage. - rmorten #
# 11/12/01 - Cleanup wasn't working since we run this file every #
# week but wanted to delete files 30 days old. Changed to 28 #
# days. - rmorten #
# 02/12/03 - Added new serial number to end of file to show finish#
# time. - rmorten #
# 02/20/03 - Corrected serial number addition with printf. #
