Hi everyone. Thanks for all your input recently on the topic of local notifications. I think we got some really interesting solutions 
Back to more prosaic matters. Most of you will know that I've been messing around with this stuff for some years. My last major change was when I migrated from Vera, which was something like 4-5 years ago.
While my system has grown, it's not really altered very regularly, although I try to keep most of it kind of up to date.
Current set up:
Intel NUC that runs:
Bare metal install of Debian
Z-way server with Z-wave.me USB stick
Openluup
Altui
Multi system reactor
HA Bridge
Mosquito
Raspberry Pi
Running Home Assistant
About 40 varied Z-wave and Wifi devices
I also have a Synology DS224+ which may inform some responses.
Home Assistant recovery is pretty simple. I get a full backup of the system every night dumped onto my SAN and I know from experience that it would simply be a case of booting up a new install and feeding it the backup.
The NUC on the other hand....
Coming from a commercial IT world, I am becoming more and more conscious that I don't really feel I have a suitable disaster recovery plan, and my core system is running on hardware heading for 10 years old.
My initial thought, which I've kept putting off as it's awkward would be to grab a nice SSD, reboot the NUC into Mint or something similar and simply do a dd copy onto a new drive. I can get a replacement NUC on ebay simply enough, and keep it in a cupboard if anything other than the hard drive fails on the existing one, but this feels rather like a stop gap. However one immediate question:
If I had to use the replacement NUC would all the Z-wave devices simply carry on talking to the stick, or would they all need to be re-paired?
How easy would it be to move everything the NUC does (as a start) onto the NAS? Create a VM and clone the disc onto it?
Should I move to Docker? Something else?
What are the hive mind's thoughts?
Apologies if we've done this before, but while it all just works...
Cheers!
