I’m duplicating my server hardware and moving the second set off site. I want to keep the data live since the whole system will be load balanced with my on site system. I’ve contemplated tools like syncthing to make a 1 to 1 copy of the data to NAS B but i know there has to be a better way. What have you used successfully?
Is this intended to handle the scenario where you accidentally delete a bunch of important files and don’t realize until the delete has synced, and deleted them on the remote site too? Consider using versioned backups too, to handle that case.
