What Is Backblaze B2?

Backblaze B2 is a cloud object storage platform that allows individuals and organizations to store, access, and manage data remotely through a pay-as-you-go pricing model. Launched to directly compete with AWS S3, Wasabi, and other major providers, Backblaze B2 aims to make high-performance, secure cloud storage accessible to businesses of all sizes. Its straightforward approach strips away complexity seen with some legacy vendors by keeping pricing, egress rules, and storage classes easy to understand and free of surprise costs.

In practical terms, users upload their files or data sets—photos, backups, AI training data, videos, or app assets—to Backblaze B2’s cloud. The platform handles redundancy, durability, and security, so teams can focus on building products rather than managing hardware or disaster recovery. Backblaze B2 leverages data centers in the US and EU with multi-region failover, offering an alternative to storing assets on-premises or with higher-cost suppliers.

As of July 2026, key differentiators include the permanent free storage tier (10GB), robust APIs, native integrations for workflows (including AI/ML), and the recently announced Overdrive performance tier. Crucially, its $6/TB/month base rate, free egress up to 3x your stored total, and transparent billing position it as a more budget-friendly and predictable solution than many "Big 3" providers. Developers can integrate Backblaze B2 via S3-compatible tools, making migration practical and minimizing vendor lock-in.

Whether you're backing up company archives, hosting web assets, running continuous integration pipelines, or supporting machine learning teams with big data sets, Backblaze B2’s model allows you to focus on scaling capacity—with costs that remain easy to explain and predict.

Key Features and What Stands Out

Backblaze B2 isn’t just about lower dollar-per-terabyte storage. Its feature set intentionally targets pain points long associated with legacy cloud vendors—namely, unpredictable costs, convoluted egress rules, and complex onboarding. Here’s what distinguishes Backblaze B2 in 2026:

1. Transparent, Predictable Costs: The foundational $6/TB/month model directly challenges the $23/TB/month charged by AWS S3 (source). What’s more, you never have to guess what you’ll be billed for pulling your own content back out. The egress model (free downloads up to 3x your stored volume per month, then $0.01/GB) keeps budgets safe for any moderately active workflow.

2. Free Egress—Generous and Simple: Egress fees have long been the elephant in the room for AWS S3 and Google Cloud Storage. Organizations discover too late that serving assets, syncing data, or distributing datasets skyrockets their bill—sometimes by a factor of five or more. Backblaze B2’s free egress policy lets you download up to three times your stored volume as part of the monthly rate—no need to track multiple thresholds. This can mean savings in the hundreds or thousands of dollars per month for projects with significant outbound traffic.

3. New: B2 Overdrive Tier for AI/ML and High-Performance Workloads: In response to rapidly growing demand from machine learning, generative AI, and analytics projects, Backblaze rolled out B2 Overdrive in 2026. For $15/TB/month, you get up to 3x higher read/write speeds. This targets organizations needing to train LLMs, process massive video volumes, or power ultra-fast web and app experiences where speed is paramount. Standard free egress policies still apply.

4. Zero API Fees for Standard Operations: Unlike AWS and Google Cloud, Backblaze B2 does not nickel-and-dime you for every API request. Upload and download GET/PUT requests are free, supporting workflows with frequent batch jobs, syncs, or archival activities without runaway costs.

5. Industry-Leading Durability and Redundancy: Data is stored redundantly in multiple physical locations to achieve 99.999999999% (eleven nines) durability, on par with the biggest cloud vendors. This is essential for any business with compliance, data integrity, or disaster-recovery requirements.

6. S3-Compatible APIs and Integrations: Teams using AWS, Google, or third-party tools can often switch to Backblaze with minimal code changes thanks to their S3-compatible API layer. This allows you to migrate workloads, pipelines, or snapshots without re-architecting your entire process.

7. Continuous Free Tier for Testing and Light Workloads: The first 10GB of data is always free, not just as a trial but as a permanent offering. This makes experimenting or storing small datasets risk-free.

8. User-Friendly Web Interface and CLI: Backblaze B2 delivers not just API access for technical users but also a clean web UI for bucket management, permissions, and usage analytics. Its CLI and SDK options are widely documented and used in infrastructure automation.

9. Cross-Region and EU Storage Options: In 2026, data residency and compliance matter more than ever. Backblaze allows users to select US or EU regions, supporting GDPR and regional compliance needs. This is critical for organizations with global user bases or strict regulatory requirements.

10. Security and Privacy: Data is encrypted both in transit and at rest. Access and bucket management offer fine-grained control with support for application keys, bucket-level permissions, MFA, and integration with identity providers for enterprise-scale deployments.

In sum, Backblaze B2 is not just about cheap storage. Its blend of predictable egress, high durability, compatibility, and high-performance options makes it a strong candidate for businesses fed up with opaque or punitive pricing from traditional vendors.

Backblaze B2 Pricing: Pricing Breakdown and ROI Analysis

The heart of Backblaze B2’s value proposition is its radically simplified cost structure. Let’s deconstruct how the various plans and costs add up, real scenarios for egress, and ways to optimize for the lowest total cost of ownership in 2026.

Storage: B2 standard tier is $6 per terabyte per month—with no minimum storage period or hidden retrieval fees (source). Unlike Wasabi, which requires a minimum 30-day commitment for each file, Backblaze B2 offers genuine pay-as-you-go, letting you delete files anytime without penalty. If you need even more speed, B2 Overdrive costs $15/TB/month and is tuned for AI/ML workloads or I/O-heavy enterprise builds.

Free Egress Allowance: Store 1TB, and you get up to 3TB of downloads per month included for free. Only egress past this threshold is charged at $0.01/GB, a fraction of what AWS S3 or Google Cloud would bill you for outbound data. For context, S3’s standard egress rate is $0.09/GB and often charged after just 1GB/mo (source), making Backblaze 80%+ cheaper for most download-heavy workflows.

B2 Egress Fees in Practice: Many users find egress hard to predict, so let’s run an example: A small business stores 4TB of assets, serving about 7TB/month of downloads. Their first 12TB (3x4TB stored) is included free. They pay $0.01/GB only on the remaining downloads—so just $30 if they go 3TB over that free allocation. With AWS S3, those 3TB over the free limit would cost $270. In persistent, high-output use (think SaaS apps, media distribution, or ML data staging), these savings add up fast.

API Requests: GET and PUT operations are free—no per-request charges. This sharply contrasts with AWS S3, where high-volume read/write activity can add up to a significant surprise on the monthly bill, especially for enterprise or programmatic access patterns.

Reserved Capacity Pricing: Customers with predictable needs can opt for “reserved capacity” plans for additional discounts. These typically start at 20TB and lock in lower storage rates for a multi-year term. Details are custom, and official quotes are handled via Backblaze sales.

Free Tier: The 10GB permanent free storage tier plus 1GB of free daily egress makes B2 an easy fit for hobbyists, startups, or testing scenarios—no timeouts, no credit card required.

B2 Overdrive Pricing: For $15/TB/month, you get up to 3x throughput for I/O-bound, AI, and data science workloads. This options targets devs running real-time pipelines or rapidly training ML models. The B2 Overdrive tier otherwise follows the same egress and API structure as the main plan.

Hidden and Miscellaneous Costs: There are no setup or account maintenance fees. Unlike AWS, which charges for “early deletion” or API throttling, Backblaze B2’s transparent approach means what you see is truly what you get. The major extra fee to watch out for is if your workflow requires more egress than 3x your monthly storage allocation—then, you’ll need to budget for the $0.01/GB charge on top.

B2 Storage Cost Calculator: Backblaze’s web-based calculator helps organizations forecast costs for variable storage and download scenarios, even factoring in changing workloads or deleting files mid-month. It’s advised to test your usage there (source).

ROI Perspective: For most active SaaS, web, or AI teams, the ability to forecast total monthly cloud storage costs with confidence—and avoid 400%-500% swings in egress line items—can be transformative. Customer case studies reported hundreds to thousands in savings per month (source), especially when migrating from AWS S3 or relying on heavy programmatic download flows.

Data redundancy and security meet or exceed industry compliance needs.
Simple billing and reliable cost estimation; cost calculators help organizations plan budgets.

Cons

Maximum egress per month (free) is capped at 3x storage—those with massive outbound data (CDNs, high-traffic streaming) may hit this quickly and incur $0.01/GB overage fees.
Storage is pure object/bucket based—doesn't offer file sharing or sync features; best suited for developers and IT, less for casual cloud file management.
Not all major public cloud regions supported—location selection is more limited than AWS or Google Cloud (source).
Wasabi’s unlimited egress policy may suit high-bandwidth customers better, provided they operate within “fair use” rules. Cloudflare R2 offers unlimited intra-CDN egress.
No built-in compute or managed serverless features (unlike AWS S3 + Lambda) as of July 2026.
B2 Overdrive costs can still add up for large AI/ML teams scaling rapidly ($15/TB/month, but much cheaper than building bare metal).

Backblaze B2 is a compelling solution for predictable, cost-sensitive cloud storage—especially when rapid egress or high performance isn’t taken for granted. It’s worth testing for backups, app assets, and as an S3 alternative. Power users needing infinite egress or advanced cloud compute may want to mix providers based on each project’s true needs.

Who Should Use Backblaze B2?

Backblaze B2 is designed for organizations that value transparency and predictable costs in their cloud storage bill. Tech startups, SaaS businesses, agencies, creative teams, and IT departments needing reliable offsite backup or large object storage are clear beneficiaries. AI/ML teams handling frequent dataset refreshes will appreciate free API access and inexpensive egress for workflows that move lots of data in and out regularly. The new Overdrive tier gives fast lanes for teams training models or running big batch jobs.

Developers migrating from AWS S3 will find the S3-compatible API layer makes the transition nearly seamless. Businesses scaling up storage or hosting assets for web apps, media, or analytics get enterprise-grade durability without the surprise fees typical of other vendors. The budgeting process also gets easier—the cost is easy to explain to finance or management with the built-in calculator and no socketed upsell items.

However, Backblaze B2 may not be ideal for every use case. Power users needing limitless, unrestricted egress or those dependent on ultra-low-latency edge locations in Asia, Latin America, or remote zones might find AWS or Cloudflare R2 better tuned. Teams seeking all-in-one platforms with bundled compute or managed pipelines may be better served by a multi-cloud approach, using Backblaze B2 alongside other cloud tools for maximum flexibility and coverage.

How It Compares to Top Alternatives

Backblaze B2’s $6/TB/month plan and free egress policy place it among the most affordable and straightforward cloud storage providers in 2026. To put its offer in context, let’s examine how it stacks up against key competitors: AWS S3, Wasabi, and Cloudflare R2—all of which are frequently cited in "Backblaze B2 vs" pricing searches.

AWS S3: As the long-standing industry benchmark, AWS S3 charges $23/TB per month in most US regions, plus $0.09/GB for data downloads beyond the first 1GB each month (source). Fees also accrue on API calls, multipart uploads, and sometimes for deleting files early. In active use, egress charges often dwarf storage costs—making AWS S3 a markedly expensive choice for most out-bound heavy workloads. Backblaze B2 sidesteps these pain points with “all-in” pricing and generous default egress allowances.

Wasabi: At $6/TB/month, Wasabi matches Backblaze B2 on headline per-terabyte pricing but markets “unlimited free egress.” However, fairness rules apply—heavy downloaders can be scrutinized or throttled. Wasabi requires a 30-day minimum storage commitment, meaning users are billed even if they delete files early. For dynamic or ephemeral workloads, Backblaze’s no-minimums approach can lead to real savings.

Cloudflare R2: Cloudflare R2 is priced at $15/TB/month. Like Wasabi, it offers unlimited free egress, but only when downloading data to other Cloudflare products (such as its CDN or Workers platform). Egress to the public internet can still incur fees or rate limits. R2 is ideal for businesses already deep in the Cloudflare ecosystem, wanting frictionless asset delivery via Edge CDN, but its per-gigabyte cost can be high for raw storage outside this scope.

B2 Overdrive vs AWS S3 Express: AWS S3 Express One Zone (premium S3 for speed) costs significantly more than B2 Overdrive’s $15/TB/month pricing and still lacks free egress policies. Overdrive specifically targets AI/ML teams, competitive with other “hot storage” services.

Performance & API Support: All providers now feature S3-compatible APIs, but AWS imposes per-request charges that can escalate in large-scale environments. Wasabi and Backblaze both offer free API requests, a critical distinction for high-churn applications. Cloudflare R2’s S3 compatibility is nearly complete, enabling relatively easy migration but with some differences in auth and region handling.

Hidden Costs Comparison: Both AWS and Wasabi may add costs for early-deletion, minimum retention, or errant API call bursts. Backblaze B2, in contrast, publishes all rates openly—making “hidden” charges almost nonexistent for standard operations. For organizations needing to forecast costs accurately, this may be the most significant differentiator of all.

Where Backblaze B2 Is Best: Small to medium businesses, SaaS teams, and agencies seeking an affordable S3 alternative for archiving, serving, and collaborating with cloud data. Its model favors those with a moderate but predictable storage and download profile.

Where Another Solution May Win: Media companies serving hundreds of terabytes/month at peak, or product builders deeply integrated with Cloudflare or AWS native compute pipelines, may prefer those platforms for edge features or scale. Users who need to blend object storage with managed functions may also benefit from R2 or AWS S3 + Lambda packages, albeit for a higher price.

For most businesses, Backblaze B2 is the budget-friendly, reliable middle ground—a mix of the best from both budget and performance worlds, with clear, documented pricing and no guesswork.

Best Alternatives to Backblaze B2 in 2026

While Backblaze B2 remains a favorite for transparent and affordable object storage, some users might still prefer a different provider depending on needs and preferences. Here are some of the leading alternatives in 2026:

Wasabi continues to be a direct competitor, offering the same $6/TB/month pricing with unlimited free egress. Their “fair use” egress rules mean some ultra-high-bandwidth customers (such as streaming services) could run into limits, but for most business backups and content storage, Wasabi’s model is remarkably similar. Note that there’s a 30-day minimum storage charge per file.

Cloudflare R2 targets developers who want boundless egress (at no cost) but only when serving data to end users via their own CDN or serverless platform. Their $15/TB/month storage cost is higher than Backblaze B2, but for web apps built in Cloudflare’s stack, R2 can mean $0/month egress, undercutting AWS and minimizing costs for global content distribution. It's best for teams who want tight CDN integration and already use Cloudflare Workers or Durable Objects.

AWS S3 remains the industry benchmark. Despite high storage and egress costs, it’s unmatched for feature depth, region coverage, integrated serverless compute, and tooling ecosystem. S3 makes sense for enterprises committed to AWS, or those needing global disaster recovery, sophisticated permissions, or advanced event-driven architectures.

Google Cloud Storage and Azure Blob Storage are worth considering for large enterprises that already have vendor relationships or require unique AI/ML integrations. Both vendors have matching features and sometimes offer promotional deals for startups and large migrations.

TL;DR: If absolute egress flexibility is non-negotiable, consider Wasabi or Cloudflare R2. For blazing-fast compute integration, AWS S3 is still the king—at a steep price. For value-focused teams who need reliable, scalable, and simple storage and downloads, Backblaze B2 remains a top contender in 2026.
