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.

Unreliable For Business Use Unreliable For Business Use We used Backblaze, but they closed our account due to a fake DMCA complaint without verifying its validity or checking for the existence of files in our account. Their customer support is unreliable and often response is computer-generated AI nonsense. I wouldn't recommend using them despite their good pricing model. We were not even given the chance to move our files. Luckily we have a backup with Digitalocean otherwise we were secrewed.

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.

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.
