With those cron jobs in place, the backup will run every night. Those cron jobs would something look like:Ġ 22 * * * /path/to/vm-stop.sh >/dev/null 2>&1Ġ 0 * * * /path/to/vm-export.sh >/dev/null 2>&1Ġ 2 * * * /path/to/vm-stop.sh >/dev/null 2>&1 For example, you could run the stop script at 10 p.m., the export script at midnight, and the start script at 2 a.m. You’ll want to make sure to separate them with plenty of time for each to successfully run. Move your scripts to a directory of your choice and then create cron jobs for each one. Give each of these files executable permissions with the commands: VBoxManage startvm "Web01" -type headless In that file, paste the following contents (altering the contents to fit your needs): The above file will append today’s date in the file, so you won’t overwrite your previously exported OVAs.įinally, we’ll create a script to start the virtual machine with the command: Remember to change the details to match your needs. VBoxManage export "Web01" -o /data/Web01-$.ova Next, we’ll create the script to export the VM with the command: Where USER is the name of the remote admin user and HOST is the IP address of the VirtualBox guest VM. The first script will power off the machine. This is where it gets a bit tricky because in the automation you have to create three bash scripts: Ssh-copy-id you’ve taken care of that, you can then issue the poweroff command as listed above and then export the VM to the. Make sure to copy your SSH key from the host to the guest with the command: ![]() ![]() Of course, to make this work via a script, you’ll need to set up SSH key authentication. How do you pull this off? You have to do so via an SSH session like so: Using the VBoxManage poweroff command could cause data loss, which we want to avoid at all costs. The best way to do that is to power off the VM from within the guest. When it completes, you should see the /data/Web01.ova file ready.īefore you issue the command, the machine must be powered off. ![]() That command would be:ĭepending on how large the VM is, the command could take some time to run. ova file housed in an external drive mounted on /data.

To find out the names of all your current VMs, issue the command: The first thing we need to know is the name of the VM to be backed up. This backup will come by way of a bash script. You’ll also need a drive with plenty of space to back that VM up to. To work through this, you’ll need a running instance of VirtualBox with at least one VM available to back up.
