RaQ 550 Simple Back Up

This program will do full backups every Sunday and on the 1st of every month.  
During the week, it will go ahead and do partial backups.  Every file is stored in: 
/home/raqbaq/arch for easy access, and the ownership is changed to 'admin', 
for easy download.  Doing such applications as 'ncftpput', you can store the 
backups on a remote FTP server as well.

#!/bin/bash

# This application will do FULL backups weekly
# and parial backups during the week.Updating only files modified since the backup
