POE Next cloud Server

Dual Pi next cloud server.
One pi will run the service while the other will be a sync server to keep a backup of the photos and videos.
My goal with this is to become less dependent on Google drive and save some monthly fees. Currently at 2.5 TB on storage because I consolidated one drive and aws. Lots of duplicating files to sort.
I have two 4TB desktop drives laying around so why not use them.
