What is your cloud backup solution?

I’m interested to hear what do people use as their cloud backup and the cost of it. I currently use idrive e2 storage at 5$ per TB a month. Trying to see if there is any better deal anywhere and just curious on everyone’s thoughts.

I use Filen, I don’t know if they still do it but you used to be able to buy a lifetime plan for a one-time fee that was like 50-100GB or something like that, and you could stack them. So I just bought several during a Black Friday sale.
