Website: backblaze.com/b2
Backblaze B2 Cloud Storage is the most cost-effective S3-compatible object storage platform, delivering enterprise-grade reliability at 1/5th the price of Amazon S3. With straightforward, transparent pricing and no hidden fees, Backblaze has become the preferred choice for backup vendors and cost-conscious organizations. The platform stores over 2 exabytes of customer data across its infrastructure and integrates seamlessly with 700+ backup and storage applications through its S3-compatible API.
Backblaze B2 provides hot cloud storage accessible within milliseconds, making it suitable for both active backups and archival storage without the complexity of multiple storage tiers. The platform's radical price transparency eliminates surprise charges—what you see is what you pay. Unlike competitors with complex pricing matrices, Backblaze charges one flat rate for storage and straightforward egress pricing with generous free allowances.
The service leverages Backblaze's unique expertise in storage reliability, developed over 16 years operating their consumer backup service protecting over 750 petabytes. This operational knowledge resulted in custom-designed Storage Pods—high-density storage servers that deliver enterprise durability at commodity costs. B2 provides 99.9% uptime SLA and 99.999999999% (11 9's) durability, matching enterprise providers at a fraction of the cost.

Backblaze partnered with leading CDN and cloud providers to offer FREE egress when accessing B2 data through these services:
Zero-cost data transfer when serving B2 content through Cloudflare CDN. Perfect for backup web portals.
Free egress when using Fastly CDN, ideal for distributed backup recovery scenarios.
Reduced or eliminated egress charges when combining B2 storage with Bunny CDN delivery.
Over 700 applications natively support Backblaze B2, including:
Scenario: 10TB backup storage, 100GB monthly uploads (incremental), 50GB monthly restores
Compare to AWS S3 Standard: $236/month (293% more expensive!)
Annual savings: $2,112 by choosing B2 over AWS S3
Backblaze B2's transparent pricing eliminates the budget uncertainty that plagues AWS and Azure users. With simple per-GB pricing and generous free egress allowances, organizations can accurately predict costs without surprise bills. The 3x free egress policy means typical backup operations—occasional restores and testing—incur zero transfer charges, a stark contrast to AWS's $0.09/GB egress fees that can exceed storage costs.
The platform's S3-compatible API provides enterprise features without enterprise complexity. Object Lock, versioning, and lifecycle management work identically to S3, enabling seamless migration from AWS while reducing storage costs by 75% or more. For backup vendors and MSPs, B2's predictable pricing enables profitable service offerings where AWS margins would be razor-thin.
Backblaze's operational transparency and customer-first philosophy, demonstrated through their annual hard drive reliability reports and open-source Storage Pod designs, builds trust that closed-ecosystem providers cannot match. With over 16 years protecting customer data and 2+ exabytes under management, Backblaze proves that affordable and reliable are not mutually exclusive.
