Shouldnt do so that bad. my raspberry pi 4b can do jellyfin and nextcloud without pushing 15W at full load.
x86 is inefficient, especially older models, but youll likely only push anything over 10W when actually streaming something that requires transcoding. Most of the time your home server is gonna sit idle or doing some tiny cron job that won’t really blast the CPU at all.
Rsync over FTP. i use it for a weekly nextcloud backup to a hetzner storage box
