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.

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 They failed to review our account utilization when their system fails to properly remove outdated files based on the set policy.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!

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!

Woeful product and even worse customer service. AVOID!! The one time I needed to use the download function, their software does not work and then the backup was missing lot of important files from months earlier even though it was on continuous backup. Their customer service is a joke. Do yourself a favour and avoid at all costs
