off site backup of unraid server to another unraid server

[jumpnjet22]

Hi I'm trying to find a way to back up a local Unriad server to an off-site unriad server, securely without having to pay for a subscription fee

Thanks

A combination of dockers duplicati + letsencrypt + (nextcloud or minio) will work. There are multiple threads discussing these options.
