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 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.

TERRIBLE customer support This service is the WORST! Expensive and their crappy Zendesk support is a joke. No way to contact them via phone. They're supposed to be available via chat during business hours, but I've been trying for WEEKS to get assistance. They just send links to outdated Help articles with poorly written, incomplete instructions.

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.

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.
