This is a simple script that dumps a mysql database, moves it to the web directory and tar gzips it. The script then copies it to a remote server, deletes the original file and emails you to tell you it has finished.

Note - you’ll need to set up key based authentication between your servers. Note - don’t enter a passphrase. Other than that - look here http://www.debianadmin.com/ssh-your-debian-servers-without-password.html

If the script is of any use to you feel free to modify use and do as you wish with it.
