This is probably not the answer you are looking for, but I use SMB for the backup. That works pretty well, and I had no issues whatsoever. I didn't open ports for that because I only do backups when I'm home, and if I do need my backups, I access them via Tailscale (VPN). It was pretty simple to set up.
If you have questions about the setup process, DM me.
