See my comment about Resilio sync above

Resilio sync works great for that since syncthing is on the out. I actually prefer Resilio anyways

I know I’m in a different situation here but i buy all my server drives off ebay. Just got ~60TB worth of SAS drives for a little over $200 USD. Ive never had an issue. Must of these place are where business sell their drives to be wiped. Then they just put them to on ebay

What features are those?
