Disclaimer: I work at Backblaze. For our Personal Backup product (fixed $5/month for as much data as you can keep on your laptop) your data is encrypted on your laptop BEFORE UPLOADING to Backblaze, and we have no idea what is inside your files and I assure you we don't want to know. (Look into setting your own private encryption key if you are worried at all about this.) In our 10 year history we have never once removed a customer's file because we objected to the file contents in that customer's Personal Backup because we simply don't know what is in the files. For our other product line (B2 Cloud Storage for half a penny per GByte per month) the problem is you can have a "Private" bucket at which point we absolutely DO NOT care what you store. But if you have a "Public" bucket that is a public website. If you have public bucket serving up illegal content such as a phishing website or sharing bootleg songs or movies that you do not have legal rights to share, then we may shut you down (turn the bucket "Private" so nobody but you can get the data). TL;DR - use our Personal Backup product or a "Private" bucket and store WHATEVER YOU WANT. But if you break the law serving up a website from Backblaze we have an obligation to shut you down.
