i know this pfsense chat but you seem very smart in this other stuff too i had another question if i have a unraid and it rsyncs to a freenas if data on teh unraid bit rots wont it bit rot the freenas or should i be scrapping unraid all together. i just like it its easier to use then freenas but i do like some things freenas has so there is no happy medium or best solution windows i guess lol
