Dodgy billing practices The Good: I've found Backblaze to be unobtrusive and just gets on doing its thing in the background. When I've needed to restore files, it's worked. The bad: There is no way to cancel auto-renewal of the subscription without deleting your backup and stopping your service the day you stop the auto-renewal. Pick your word for this: dodgy, wrong, unethical, robbery.

Only useful in some cases Pros: very fast, doesn't hog CPU or memory like CrashPlan Cons: deleted files are only retained for 30 days. Backblaze is essentially only useful in cases where a hard drive completely fails / external hard drive is physically broken. If a hard drive starts slowly corrupting over time, or if you accidentally delete files and don't realize it within the 30 day limit, you're screwed. Absolutely useless in those cases.

It sucks It sucks! massive price increases and all kinds of sleazy tacktings to prevent you from cancelling the renewal.

Support is absolutely terrible Support is absolutely terrible. All you get is canned responses and ZERO actual care for your specific issue. One of the worst customer support experiences EVER.

What an awful service What an awful service. Their backup client is terrible, expensive, and so slow it's worthless. I regret signing up with this useless service.
