As someone who only needs to backup 10TB, I looked once at getting into tape - the cost of getting a tape drive and a way to connect it to my computer was eye-watering. The very long-term prospects were even worse: I’d have to choose between buying multiple LTO-n tape drives for redundancy, or keep upgrading every 7ish years or so, which entails buying more tape drives.
I’ll stick with my 10 2TB hard drives, zfs, and biannual swaps to new hard drives, sadly. At least I won’t ever have to deal with more than 10 hard drives at time, assuming $/GB never increases.
At some point I should start sticking a Windows hard disk image on there; .vhd will still probably be readable and bootable in a VM 10 years from now.
