Backup behavior without going through Homebridge UI
### Current Situation

I run homebridge out of a VM, so I'm currently rsyncing the homebridge backups directory to a network mount. I've used the UI a few times to do backup/restores now, and it's always gone smoothly. Two questions:

1. If I spin up a fresh install of Homebridge, then drop my copy of the /backups dir into the same dir as the fresh install, will that "just work"? Will the UI see it has backups that don't match the current state and attempt to initialize? Just trying to understand the expected behavior. I did see this small call out in the [wiki](https://github.com/homebridge/homebridge/wiki/Backup-and-Restore#backup-and-restore-without-the-homebridge-ui) but it didn't have the details I was looking for. 
2. I'm doing the rsync on cron, but feeling a bit lazy to wire up notifications on failures. If I set the directory to the network mount using [scheduledbackuppath](https://github.com/oznu/homebridge-config-ui-x/wiki/Config-Options#scheduledbackuppath), will the UI surface error notifications if the scheduled backups fail to write correctly?

Of course - happy holidays to you! A massive thank you for build and supporting this wonderful project. It has made HomeKit a billion times more useful/effective in so many ways.
