Backblaze B2 is 6$ a month for 1TB and first 10GB is free. You pay proportionally (it cost me 2-3$ for last 7-8 months for 20-150 GB that accumulated over time). Keep in mind that you will spend more if you download backup, but you should use cloud backup as last resort anyway. I backup to 2nd local disk and also to B2 daily with Kopia. Didnt need backup fortunately, downloading from B2 small files ocasionally just for testing setup
Its not just cheaper, I love it because I dont have to deal with Gshit company
