I think it's good enough. Shut down as many services as possible if you want to be safer. In the end it would just be like booting after a power failure.

it would just be like booting after a power failure.

That level of confidence is EXACTLY what I want when I'm restoring a backup.

The difference being that it should just be writing log files and nothing important.

Do you have experience of restoring such a backup?

Yeah, didn't have any problems. But maybe I just got lucky.
