Hi sifus. Please critique my NAS set up to back up photos and videos from me and wife phone.

I have a RPi4, connected to two WD Blue 1TB HDD using cheap Maiwo docking station.

The first WD Blue is the main HDD. The second is the clone. I clone once a month manually using Rsync.

The Pi and HDD is not always on. Only on when we need it.

Please criticise. Thank you.
