As an old man of computing, first program 1969, and thought networks were pointless, my comments are probably not worth much but here goes anyway.
If you Data is not on media you own, it’s not your data anymore. If you keep your backups online (powered up and attached to the machine) they are not backups. Every few years as the price point comes down buy larger disks, copy your data, and put the old disk in the equivalent of your socks draw.
You will loose data , just not all of it.
