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.

Black hole of customer service If I could give negatives stars (black hole perhaps) I would. I have been working over a week trying to get the software working since an upgrade of their software last week - and getting incomplete instructions or the same, non-solution solutions for something that probably needs tier 2 support. After 3 tries of reinstalling the software and trying to inherit my original account, I tried one last time. Only to discover that software limitations won't display more than 3 items so won't even display my original account to choose and so I am now DOA. Once again waiting for a couple of days to hear back from customer service. Unless I get resolution this time, I'm cancelling and going with another product. There are no phone numbers to call and trying to resolve complex problems via emails that happen once a day is not adequate customer supsport.

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!

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 They just send links to outdated Help articles with poorly written, incomplete instructions.

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.
