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 They just send links to outdated Help articles with poorly written, incomplete instructions.

TERRIBLE PRODUCT I used Backblaze for a few months and then when I upgraded my computer to Sonoma it quit working and there was an annoying pop up window that said my computer was not backing up. When I contacted support they sent back a super complicated solution and the links they provided did not work. Furthermore once you download their product you cannot uninstall it by yourself. They built that into their product. DO NOT USE THIS SERVICE OR PRODUCT!

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!

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.

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.
