# Purpose - To ensure that the correct options are always used when
#           performing a system backup with the ufsdump command.
# 
#           This script takes one argument which is assumed to be a
#           filesystem name, it uses the u option to update the 
#           /etc/dumpdates file, and it asks the user which dump
#           level number should be used.
#
# Name: backupscript.sh
#
