Lto tape. But I only have 15tb
It quickly becomes cost effective when you actually need the data to be safe. Far easier to have off site backups. I have never had a problem , but I like to have offline backup. Most of the time my data is static. So I am only backing up projects files ans changes for the most part.
If you have 40+ tb of dynamic data I can’t help there.
Edit: I buy used drives that are usually 2 generations old, so I got lto-5 drives when lto 7 was new. The used drives may be less reliable but used drives can be 1/10th the price of the newest ones.


It's always great to see how the EU handles IP and large companies compared to the US.
If the articles series of events and statements are true I wonder if the hackers will win. The company initiating the lock initially created a state where un-serviced trains locked up. It seems a straightforward case of bug fixing that is allowed in EU law.
