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.

Unreliable; backblaze LOSES LOTs of files!! I have had the year plan for a year, on 1 computer, with 1 big external drive, about 1.3 TB of total data. But whenever that drive was disconnected, Backblaze would begin deleting its backed up files, after just 2 days! The Backblaze docs claim that it will hold my files for 30 days, but it begins losing or deleting them after just 1 or 2 days!! I have contacted support a year ago about this, but nothing was improved, the problem persisted constantly. It was also extremely difficult to cancel the recurring $99!

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…

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.

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.
