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.

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

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.

Best unlimited backup provider in 2023 No idea what most people on here are complaining about, if you check at least once a week, which takes ten seconds, to see if the backup is actually progressing, there will be no issues when restoring later down the line. The 500GB zip limit makes sense to some extend, since this solution is not meant for storing 10's of terabytes as some gladly would use it. I had no problems over the years and recommend them as a good backup provider for a good cost per month.
