I recreated the pool, now leaving the data on a single drive outside of the pool, assuming that it needed to be copied directly to the pool.
Currently, one of my main issues is that I have Pool drives at D and all my main files on E: which is outside of the pool
Currently using teracopy to copy the files from E to D for back up, the teracopy keeps crashing?? I have no idea why.
I dont specifically have to use the pool/ D for plex, as I can connect it to E, just as a backup of data, but as the database grows it was formerly 20TB it will become problematic.
I have been through unraid, MS storage spaces, QNAP NAS (Outgrew it) etc.. This is my latest attempt without moving to a large commercial solution which just seems overkill. I have built my own server with 20bay expansion, I just need the right SW solution to manage backup and rebuilding from drive failures.
