#This script was written for some specific servers that I administer. However, it should not be hard to adapt it to your   enviroment. Just change the location of the 'CMD...' vars if necessary. Obviously you will need all the applications and   executable permissions to all the applications below to get the output we want. Generally it is best to run this script as root. You will probably want to setup a cron job to run this script on a regular basis.   

##If you choose not to use a certain application or part of this script you _must_ comment it out.  Otherwise the script   will throw errors when you run it.  


###Note:  I am positive there are more efficient ways to accomplish this same task.  This is just something I threw        together in a day. If you have  any suggestions please email me them.


##Define file name
#File will be put in the same directory as this script.  So you will need write permissions.

##Does file exsist?  Yes, create 1 backup.  No, create file.
