Hi. I would like help/ advice to setup a NAS (about 10TB) so my family (4 people) can connect their computers to store files (homework, documents, excel, photos, family video, etc). That's it for now. And I would like to set up another NAS (?) or maybe just an external drive (?) to back up the files in the family NAS automatically, like nightly. Lastly, setting up another NAS at my parents' house to backup regularly what's in the family NAS automatically, weekly (?).
We don't plan to stream video like Plex or Jellyfin. We don't plan to upload trip photos while vacation. I don't know if an old PC build (OMV, TrueNas, UnRaid but I have never used any of them before) or a prebuilt system like Terra Master, Qnap, UGreen is better. Synology with the propriety hard drive is a turn off. I don't mind spending sometime to learn and build my own, but if there is a reasonably priced prebuilt option, I am also open to it.
I have an old HP PC with like 2 open SATA. I see mini-PCs are not too expensive but there is not much internal drive storage. Any help would be great.
Thanks for any help with a setup like this.
