Backblaze waives egress up to three times stored data

The workload

Backblaze B2 prices object storage on a third model, distinct from both AWS CloudFront's paid, tiered egress and Cloudflare R2's flat zero-egress policy documented elsewhere in this batch: a free-egress allowance sized to how much is stored, plus a separate, unlimited waiver when content is served through named partner networks. The workload is again architectural, deciding whether to route reads through a partner, rather than administrative. Backblaze's own pricing page, retrieved 16 September 2026, states the base terms as verified vendor fact: storage costs "$6.95 / TB / mo," with "the first 10GB storage is always free."

What the documents show

The same page states its verified free-egress policy in specific terms: customers get free egress for downloads "up to 3x their average monthly storage," tying the no-cost allowance to how much data is kept, not a flat monthly cap. Beyond that ratio, download pricing is $0.01 per GB. The page separately names partners, Fastly, Cloudflare, bunny.net, CacheFly, CoreWeave, Equinix Metal, Vultr, and phoenixNAP, through which egress is unlimited and free regardless of the ratio, under what it calls the Bandwidth Alliance. A second document, Cloudflare's own Bandwidth Alliance page, corroborates the arrangement from the partner side as a separately verified source, describing the alliance as "a group of forward-thinking cloud and networking companies" committed to "discounting or waiving data transfer" fees "for shared customers," though it does not itself name Backblaze or list per-partner conditions; those terms are stated only on Backblaze's own page.

The operating cost

For a workload storing 1 TB and downloading 2 TB monthly, within the 3x free-egress ratio, Backblaze's stated rates would charge $6.95 for storage and $0 for egress, an estimate applying the page's formula to an illustrative volume. A workload downloading beyond that ratio, say 4 TB against 1 TB stored, would owe $0.01 per GB on the 1,000 GB exceeding it, or $10, atop the $6.95 storage charge, again an estimate, not a vendor-published total. Routing the same traffic through a listed partner removes the egress charge entirely, per the pricing page, regardless of the ratio.

The stop condition

The documents name the 3x ratio as the point standard egress charges begin, and the partner-CDN list as the condition removing that limit entirely. Whether Backblaze's total cost beats CloudFront's or R2's for a specific workload is not stated by either document and is not calculated here, since it depends on storage volume, download ratio, and whether a partner CDN is already part of the architecture, a comparable, stated workload this entry does not have.

• Does this workload's download-to-storage ratio stay under 3x, or does it need a partner CDN to avoid egress charges?
• Is one of the eight named Bandwidth Alliance partners already part of this app's architecture?
• Does Backblaze's own page, not a third party's summary, state the exact condition for this specific partner integration?

Backblaze's ratio-based free egress and partner-CDN waiver are both stated on its own pricing page as retrieved on 16 September 2026; no comparative total-cost figure against CloudFront or R2 is asserted here without a stated, matching workload.
