Is there a way to back up my current configuration?

I was wondering whether there is any way of imaging the hard drive on the Apple TV 1 and restoring it to a known good state from the backup if anything goes wrong?

I ask because I’ve had to reinstall my system a few times after getting one thing or another wrong. It would be nice to be able to start over with something like a clean slate but with essentials already installed and correctly configured.

There’s a backup utility via My OSMC
