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.

Woeful product and even worse customer service. AVOID!! The one time I needed to use the download function, their software does not work and then the backup was missing lot of important files from months earlier even though it was on continuous backup. Their customer service is a joke. Do yourself a favour and avoid at all costs

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.

Support is absolutely terrible Support is absolutely terrible. All you get is canned responses and ZERO actual care for your specific issue. One of the worst customer support experiences EVER.

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.
