From the B2 page: https://www.backblaze.com/b2/cloud-storage.html https://www.backblaze.com/b2/cloud-storage.html "Reliability: 99.999999% durability."

the OP misquoted S3s durability guarantee. Its 11 9s.

...but in a single day datacenter, which realistically drops several "9"s from that guarantee when you consider tail events. I like b2 and am using it for backup in some projects, but unfortunately it's still not an appropriate choice as a primary data store. The common counterargument I've heard is that you should have multiple redundant storage providers that you manage at the application layer anyway. Problem with that is, there are a near-infinite number of things I "should" do, but very finite resources to do them. S3 backs up across multiple availability zones by default, so using it means one less thing I have to spend brain cycles worrying about.

  Yep - I agree with you 100%, just pointing out what their page says. I'd love to see B2 get more data centers around the world - when we have to do a 500GB restore on a server in Germany, it's already slow even pulling from S3 - with B2 it would be even slower.

    Curious - if we open a region in Europe, do people care where?

      I know many German companies require you to store data on servers also located in Germany. (But I have no idea if it's similar in other countries.)

        Is it within Germany, or is it just within the EU? Restricting it to Germany would seem anti-competitive on an EU level, which is usually not allowed. But I don't know the laws.

        Depends. But if there are rules about keeping it in-country, you should consider storing it not at a storage provider. Mostly, it is important to keep the data in the EER. So germany is fine. Moving data out of the EU is a big issue, although I have been using B2 but encrypt my data first myself.
