I'm confused how this comment got rated "-10":
I use Backblaze now and once I get my NAS, I’ll probably end up using a B2 based backup. But let’s make an honest comparison. Backblaze does not replicate your data across data centers. The standard S3 storage class does (0.23/gb). The comparible storage class for S3 is one zone infrequent access (.01/gb). B2 still comes out ahead, but I wouldn’t use either one for primary storage. For thier suggested “3-2-1” backup strategy, sure. Then again, just for backup, I could use S3 glacier for $.004/gb. That’s cheaper than B2 and I get multiple AZ storage. The data charges would be higher - but its backup. If catastrophe struck and I lost my primary and my local backups, getting my data fast is the last thing I would worry about.
