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.

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.

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.

Great to upload, impossible to restore Awful, the download speeds (and reliability) mean I haven't been able to successfully download a file for a year and have now just deleted and given up. So poor, go to iDrive, bigger limits and faster restores that work.

Unaccountable, Faceless and less than accomodating service Their support team only send pre-generated responses to your concerns. They failed to review our account utilization when their system fails to properly remove outdated files based on the set policy. Also, their download costs are through the roof. We were charged several thousand when some 3rd-party unrelated to our company downloaded several 100TB of our data. They have no accountability for failures in their automated platform. Avoid like the PLAGUE!
