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!

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.

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.

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.

What an awful service What an awful service. Their backup client is terrible, expensive, and so slow it's worthless. I regret signing up with this useless service.
