I am supposing this will not work - simply using dd to copy the booted disk /dev/sda for example to a file on an external hard drive. This would not be a good back as too many system file would be missed. right?

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.
Do you have experience of restoring such a backup?
Yeah, didn’t have any problems. But maybe I just got lucky.
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.
