Backblaze B2

Backblaze B2 — Cheap US and EU object storage with free egress up to three times stored volume. B2 is the storage half of a company that made its name on consumer backup, and it prices accordingly: USD 6.95 per terabyte per month with Class A, B and C API calls all free on pay-as-you-go, so uploads, downloads and listings cost nothing per request. Egress is free up to three times your stored data and USD 0.01/GB after that, and transfer to Cloudflare and Fastly is free under the Bandwidth Alliance. There is no Australian region — the nearest locations are US West and Amsterdam. Built by Backblaze. Founded 2007.

We track it in 1 comparison — S3-compatible storage — so every claim below is a cell in a table you can open and check rather than an impression. Across those rosters it sits against 11 other tools, and what follows is where it visibly separates from them.

Where it wins.

• True cost /mo (USD) — $26.95 /mo, 3rd of 9.
• True cost /mo (AUD) — A$40.96 /mo, 3rd of 9.

Each of those is ranked against the whole roster on its category page, not against a hand-picked subset, so a first place here means first of everything we list.

Where it gives ground.

• Sydney region — No. Wasabi records Yes.
• Replication model — single-az, 8th of 12. Tigris records multi-region.

None of these disqualify it on their own. They are the fields to check against your own requirements before you commit, because they are the ones where a competitor genuinely does better.

Provenance. 27 of 28 tracked fields carry a value for Backblaze B2, and 16 of those cite a document you can open. Last verified 2026-07-23. Every figure keeps its own provenance — measured by us, claimed by the vendor, inferred, or community-reported — and we would rather print a dash than a guess.

Its nearest neighbour in our data is AWS S3. Backblaze B2 is ahead on True cost /mo (USD) ($26.95 /mo against $472.6 /mo) and Egress $/TB ($10 /TB against $90 /TB). AWS S3 takes Sydney region (Yes against No) and Official MCP server (Yes against No). That pattern repeats across the rest of the roster — see Backblaze B2 alternatives for the other rivals, each compared the same way.

The sensible middle: cheap, boring, feature-complete enough, and the Bandwidth Alliance makes egress free outright if Cloudflare or Fastly is already in your stack. The absence of any APAC region is the single reason to rule it out for Australian workloads.

Backblaze B2 is the right call in these situations, each one drawn from a field we actually record:

• Backup and archive targets where object lock matters and latency does not.
• Anyone already serving through Cloudflare or Fastly — egress becomes free.
• Workloads whose egress genuinely stays under three times stored volume.
• True cost /mo (USD) is your binding constraint. Backblaze B2 records $26.95 /mo, 3rd of 9 in the S3-compatible storage roster.
• True cost /mo (AUD) is your binding constraint. Backblaze B2 records A$40.96 /mo, 3rd of 9 in the S3-compatible storage roster. We define that field as the same computed scenario as the USD column, converted at a fixed 1 USD = 1.52 AUD, struck 2026-07-23.

Reach for something else when any of the following is a requirement rather than a nice-to-have:

• Sydney region. Backblaze B2 records No on the S3-compatible storage table. Wasabi records Yes on the same field. If that is a hard requirement rather than a preference, start elsewhere.
• Replication model. Backblaze B2 records single-az, 8th of 12 in the S3-compatible storage roster. Tigris records multi-region on the same field. If that is a hard requirement rather than a preference, start elsewhere.

We publish this block because a comparison that only lists what a tool is good at is marketing. Every figure above sits on the same page as its source, and the field definitions are on the category tables if you want to check how we measured them.

What we don't know. 1 of the 28 fields we track for Backblaze B2 are still blank: True cost from Sydney (AUD). Those render as dashes rather than as zeroes or assumptions, because an empty cell and a bad cell are not the same thing and only one of them is honest. If you know any of these figures and can point at a document, tell us.
