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.

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.

I used Backblaze for a year, never again. I used Backblaze for a year. The install was simple and service worked flawlessly. The problem came when I found I was not going to need the service for awhile. When I got a renewal notice, I went to disable autorenewal but there was no such option. The only option is is cancel the service and give up the time you've already paid for or, wait till exactly the renewal date, remember log in and cancel or you get autorewed. The response from customer support was basically FU, live with it. This is a classic website dark pattern, one the CFPB has recently put out notice on. Any company employing this sort of unethical pattern will never get my business again as their management clearly have a broken ethical compass.

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.

TERRIBLE customer support This service is the WORST! Expensive and their crappy Zendesk support is a joke. No way to contact them via phone. They're supposed to be available via chat during business hours, but I've been trying for WEEKS to get assistance. They just send links to outdated Help articles with poorly written, incomplete instructions.
