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?
Rsync over FTP. i use it for a weekly nextcloud backup to a hetzner storage box
I suggest to use sftp/ssh with rsync instead. Much more secure then FTP.
Seconded
