How can I get unlimited free egress?

Want more than 3x free egress? You’ll be pleased to know that you can enjoy unlimited free egress when downloading from Backblaze B2 to/through many of our CDN and compute partners. Partners supported for unlimited free egress: Fastly, Cloudflare,, CacheFly, Coreweave, Equinix Metal, Vultr, and phoenixNAP.

How does Backblaze's 3x free egress work?

All Backblaze B2 Cloud Storage users enjoy free data egress (also known as download) up to 3x their average monthly storage amount. The monthly average is determined based on byte hours over the billing cycle, with total egress up to 3x the average provided free; any monthly egress overage is priced at $0.01/GB.

How accurate are your rate comparisons?

The comparison charts are accurate based on published rates and select assumptions at the time of the publication. Of course, every business’ scenario is a little different so it is wise of you to apply further diligence based on your data set, workflow, and needs.

Which is better for me—getting B2 Cloud Storage service pay-as-you-go or in an annual capacity bundle?

Both services run on the same highly performant platform. Which is better for you will depend on how you wish to operate. Companies often choose pay-as-you-go when they want to scale up or down as needed, they want monthly billing to correlate precisely to service consumption, or they don’t wish to start with 20TB or more. Companies often choose our B2 Reserve annual capacity bundles when they want to buy through a preferred reseller or systems integrator or they seek to budget the exact same amount month after month, year after year, for the duration of their purchase contract.

How can Backblaze B2 Cloud Storage be priced at a fraction of the cost others charge?

Backblaze B2 is built for affordable performance. We focus on delivering always-hot service for top use cases, rather than adding expensive bells and whistles for outlier needs. We marry open source and commodity hardware with our intelligent software for high performance without high cost. And, we operate at exabyte scale for cost efficiencies.
