Backup VirtualBox Machines

A script wich grabs the name of the first .vdi file for the VM specified, makes a copy of it in a local folder and then rsync's the local .vdi archive to a remote server.

#!/bin/bash
# script to stop the VM specified, copy its first .vdi hard drive file and then start the VM again
