I’ve been searching to see if there is a way to keep two HA instances synchronized. I have two Synology NAS devices that i use as a primary and a fail-over. On the Synology, I am running HA OS on a VM. i thought about doing VM replication, but that is cost prohibitive on the Synology. i know i can do a backup and restore to the other instance, but that seems way too manual of a process. My ideal setup would be some automation that copies all data over to the backup HA instance periodically (every few minutes/hours). then if i have an issue on the primary, i can just yank the zwave stick out of it, plug it into the other NAS and keep the wife happy. has anyone done anything like this?
