Tape for home backups?

Question

Backup

Now, as a cold storage for backups, I use hard drives. However, there are already a lot of them, they are expensive enough to provide redundancy, and they do not have a cold data storage period.
In this regard, I thought about buying an LTO streamer. Cassettes are relatively cheap and have a shelf life of 15 years.
Does it make sense to take a drive with LTO-5 support or do you need to focus on newer standards?

Answer 1

Depends on the size of the backup. If you have 100500TB of data to back up - maybe. An LTO-5 cassette fits 1.5TB (3 with compression). A 4TB disk costs 6-8t.r. Is it worth bothering with finding a streamer (and ideally 2) and looking for cassettes, looking for a controller with which you will connect it (usually FC)? LTO-6 is still relevant in the enterprise, which means it is quite expensive.
