Just part of a lab built over the years. Primary storage is a Dell R730XD filled mostly with 12 TB drives all set up in a ZFS array comprised of mirror vdevs, so redundant by default plus the built in ZFS snapshots for the rare need for a rollback on a dataset.

It only recently got that big because I had a mixed set of drives going back years and finally decided to work on getting them all to the same size and picked 12 as a good cost/volume balance, can find them at used server parts shops for a bit over $100 each.

Major risk is I don't have a good auto alert for smart monitor issues, so just make sure to occasionally manually copy the vital stuff like photos to an external drive.

I have a 1tb hd. And a 1 tb backup. Manually switch on backups.

That's pretty well what I started with 20 years or so ago, had them in some little box with some funny Nvidia CPU. That go upped to a pair of 3 TB that have somewhere around 10 years uptime on them if I recall by now, and kind of spiraled from there. Rsync on a schedule is nice for that.
