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.

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.

It sucks It sucks! massive price increases and all kinds of sleazy tacktings to prevent you from cancelling the renewal.

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.

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!
