I don’t know about any newbie friendly resources, would be interested in that as well. I guess most datahoarders are also selfhosters, so I’d to look into that as well. Start small, get a smalll cheap, used computer, maybe with an external drive. Check out some docker(-compose) tutorials.
As for data corruption this is something I thought about recently as well. I have not seen a good solution, someone said ZFS with redundancy will autocorrect bitrot. Not sure if this is even possible (or practical) on a computer (can you have the redundancy in another pool partition?)
