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 I have been a subscriber for several years. My two computers are fully backed up but a lot of data seems to be missing. Due to size I cannot restore my files while i can back them up. Makes sense. I can only buy 2 backup drives for more than 400 dollars of which i will get most back if I return them but being in Belgium the shipping will already be substantial. I just want to restore in the same way that i can backup.

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

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.
