I would do something like this:
- Set up the machine with two completely separate boot environments, a
"live" filesystem and an emergency recovery filesystem on a SSD.
Configure it so
that *it boots *by default* into the recovery image, but can be rebooted
into either image by console or remote command.
- If you need to recover, log into the machine and reboot it into the
recovery image. Restore the desired image onto the live disk. Reboot
back into the live filesystem.
- If the machine has crashed badly enough that it can't be rebooted
remotely, just ask the remote site to powercycle it. It'll boot into
the recovery image and you can repair or restore from there.
