You can still buy brand new LTO-4 and up from a brief search - I think due to the enterprise use cases it’ll hang around longer than any other format. Tape existed before the HDD; it’ll be there watching HDDS pass away into the ether too. Probably a few tape drives on the Starship Enterprise somewhere.

More seriously; you can buy used lto-7/8 for very little these days, and the tapes are extremely cheap per gb. The drives are somewhat loud; it’s not a beside device for sure. I’m finding it a bit of a pain to manage a good backup strategy with them.

You put exactly why I said do not mention LTO

- You suggest buying multidecade old drives that are no longer manufactured, have weird interfaces that your 2026 PC no longer has, are expensive, large, noisy

- You then mention LTO7 which will not read your LTO4 tapes and is not just expensive but literally out of reach economically for single home

Basically LTO is a terrible backup strategy unless you have a lot of money regularly that you will spend in order to upgrade your entire equipment every two/three generations (otherwise your newer equipment wont read your old tapes). Or you have so much data to backup that cost of drives is not really an issue.

Using HDDs for backup is also a terrible long term strategy, because you must have a lot of money regularly, to buy new HDDs to replace your old HDDs and this much more often than you need to buy a tape drive to migrate your tapes.

I have stored a lot of data on HDDs, and the only reason why I have not lost any of it yet is because I have always used duplicate HDDs. After 5 years or more, most HDDs had some corrupted sectors, but they were not in the same positions in the duplicate HDDs, allowing complete recovery of the data.

The reality is that both tapes and HDDs suck. What is really needed for long-term storage is a write-once memory with a lifetime of 100 years or more, based on an open standard that would ensure the availability of readers in the future.

If such a memory would use optical reading, it would have to use a great number of layers, filling a 3D volume, in order to achieve densities comparable with the magnetic media. While several research projects in this direction have been announced from time to time, until now none of them has resulted in a commercial product.

I bought a thunderbolt to FC adapter; works perfectly on Mac and Linux.

I mention LTO 4 because you can today, buy multi decades old LTO-4. Brand new. So in multiple decades from now, I assume you’ll be able to find LTO-7 or 8; brand new. A drive might cost a little more to obtain, but given the plethora of used multi decades old lto currently out there, it seems reasonable to expect that in a recovery scenario you’ll be able to shell out for the right drive.

But yes for most HDDs or the cloud are better. No need to get spicy about it.

I'm not going to actually suggest LTO-7, but what do you think is a reasonable per-month cost for backing up your important data? If it's in the $5-$10 range then you can afford a $600 drive and some tapes.

> Basically LTO is a terrible backup strategy unless you have a lot of money regularly that you will spend in order to upgrade your entire equipment every two/three generations (otherwise your newer equipment wont read your old tapes).

"regularly" can be 10 years. Your new equipment doesn't need to read your old tapes. If you advance by 4 generations, you can buy 1 new tape to replace 10 old tapes. And the newer generations have abandoned that feature anyway.

AFAIK the tapes are cheap, but tape libs aren't. Considering that they also take up a significant amount of space, I personally don't see them as a viable backup medium for most private users.

You don't necessarily need a lib, though. Especially if you're interested in a use case where you can store data in a go bag, safe deposit box, etc., it seems like having individual tapes would be preferable.

Individual used drives aren't too expensive (or at least didn't used to be). Libraries, in contrast, do tend to be more expensive (and also a lot more trouble to ship).
