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.

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.

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

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.
