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.

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.

Perplexed and confused by poor ratings... In common with the other 5 star reviewers here, I’m taken aback by the number of bad revies for this organisation. As a photographer based in Scotland, I’ve used Backblaze to back up my images for over 6 years and have found them to be effective, efficient and communicative. Every single time I’ve reached out to them, a named individual has responded withing 24 hours and that same person has seen the conversation through to a conclusion. Having previously recovered individual images, I’ve just used them to recover 2tb of images due to me (like a total eejit) dropping an external drive. The recovery process was simple and within a week I had a 2tb drive with all my images delivered to my door. Just my opinion, but I believe that the vast majority of the poor reviews are down to user-error and people simply not taking due care when linking all their drives. I may not have used them if I’d seen these reviews, but I’ll continue with Backblaze and can’t recommend them highly enough…

Absolutely an useful service! The service is a nightmare. It works very slowly when restoring files and uses a questionable cost calculation method. I was charged $1500 instead of the $99 for my yearly plan. I recommend avoiding this service due to its lack of usefulness and poor support quality.

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.
