I don't see that as a problem. If you take a backup CD home from the office, it's also stored in a single location. The chance of your house burning down at the same time your office computer gets hacked is low enough to not worry about. Even if Backblaze replicated your backup in different locations, that only protects against their data center being destroyed. You will still lose your data if the app silently stopped working or your account gets deleted across all data centers, etc. If you really want multiple locations, then I think you should use a 2nd backup service entirely to remove that single point of failure (Backblaze itself).
