I follow the good 9pd 3 2 2 rule. Three backups, in two locations, one is remote.
First copy on an external hard drive that gets mounted only for that, then unmounted.
Second copy still at home, on a disk connected to an OpenWRT access point in the patio.
Third copy on my VPS, so remote.
Each night restic take care of all that.



I worked through three zogbee dongles from Amazon including the sonoff one.
Always had issues with my mesh. Upgrading to the one provided by Nabu guys (the v1) fixed them all and it’s been almost one year rock solid now. No more disconnection or better devices losing it
