Disclaimer: I work at Backblaze. > since B2 is a single datacenter Backblaze now has three datacenters spread about (two in Sacramento area 50 miles apart, and one datacenter in Phoenix). However, if you store exactly one file in B2, it will land in one of those three datacenters. Very soon we will allow you to choose which of the three datacenters your one file lands in. > I like a bit of extra paranoia So do I, and I would NEVER keep a valuable piece of data in only one datacenter with only one vendor. My advice to my closest friends is you value a piece of data highly, you should have three copies with three separate vendors and technologies. For example, one copy on your local laptop, one copy in Amazon S3, and one copy in Backblaze B2. You might also make sure the Amazon S3 is not hosted in the same building as the Backblaze B2. Since Backblaze B2 does not share a single line of code with Amazon S3 and no employees and a different billing system, this means a bug or network outage or malicious employee inside Amazon S3 won't affect your copy in Backblaze B2. For bonus points, use two different credit cards to pay for it that expire at different times. If you forget to pay your Amazon S3 bill, they will delete your data for sure.
