At-a-glance comparison

Backblaze B2

Cost-driven object storage for backups and media libraries, often evaluated versus Wasabi and S3 when the decision is pricing mechanics (egress + requests) rather than raw storage price.

See pricing details
  • Often chosen for cost-driven storage economics in backup and media use cases
  • S3-compatible API option supports many common tools and workflows
  • Good fit when storage footprint is large and hyperscaler complexity is unnecessary

Wasabi

Cost-driven, S3-compatible object storage commonly evaluated for backups and large storage footprints. Buyers choose it when predictable storage economics matters more than hyperscaler ecosystem breadth.

See pricing details
  • Commonly chosen for cost-driven economics on large storage footprints
  • S3-compatible API surface reduces migration friction for many tools
  • Good fit for backup and archive workflows where storage volume is high

What breaks first (decision checks)

These checks reflect the common constraints that decide between Backblaze B2 and Wasabi in this category.

If you only read one section, read this — these are the checks that force redesigns or budget surprises.

  • Real trade-off: Two cost-driven storage models: request-and-egress mechanics vs policy and pricing constraints for large-footprint backups
  • Egress economics vs ecosystem depth: Model egress, requests, and transfer paths for your workload (media delivery, backups, cross-region replication)
  • S3 compatibility vs pricing mechanics reality: Verify API surface and operational features you rely on (multipart uploads, lifecycle rules, replication, encryption controls)

Implementation gotchas

These are the practical downsides teams tend to discover during setup, rollout, or scaling.

Where Backblaze B2 surprises teams

  • Not a hyperscaler ecosystem; governance and integrations can be narrower
  • Request-heavy or restore-heavy access patterns can change economics materially
  • Region footprint and latency/performance expectations must be validated

Where Wasabi surprises teams

  • Not a hyperscaler ecosystem; integrations and enterprise governance breadth may be limited
  • Pricing mechanics and policy constraints can change fit depending on access pattern
  • Egress and retrieval behavior still matters for restore-heavy workloads

Where each product pulls ahead

These are the distinctive advantages that matter most in this comparison.

Backblaze B2 advantages

  • Clear fit for cost-driven backups/media when access pattern is modeled
  • S3-style workflows for many tools with predictable integration approach
  • Often compelling as an alternative to hyperscaler complexity for storage-heavy workloads

Wasabi advantages

  • Often chosen for large-footprint backup/archive economics
  • S3-compatible workflows for many backup and archive tools
  • Simple operational model when policy terms match access behavior

FAQ

How do you choose between Backblaze B2 and Wasabi?

Both are cost-driven object stores most often used for backups, archives, and media libraries. The right choice depends on access pattern and constraints: how often you restore, how request-heavy the workload is, and what policy terms apply. If your restores are predictable and you can model requests/egress, either can be a strong alternative to hyperscalers.

When should you pick Backblaze B2?

Pick Backblaze B2 when: You can model request volume and egress under your real restore behavior; Your use case is backups/archives/media and you want cost-driven mechanics; You’re comfortable validating S3-compatible tooling assumptions; Your restore frequency is predictable and you’re optimizing total cost.

When should you pick Wasabi?

Pick Wasabi when: Your storage footprint is large and you’re optimizing for predictable storage economics; Your access pattern is stable enough to validate policy constraints up front; Your primary use case is backups/archives with planned restore behavior; You want S3-compatible workflows without hyperscaler governance overhead.

What’s the real trade-off between Backblaze B2 and Wasabi?

Two cost-driven storage models: request-and-egress mechanics vs policy and pricing constraints for large-footprint backups

What’s the most common mistake buyers make in this comparison?

Assuming both are ‘cheap S3’ instead of modeling restore frequency, requests, and policy constraints that change total cost

What’s the fastest elimination rule?

Pick Backblaze B2 if: You want cost-driven mechanics and can model requests/egress based on real restore and access patterns

What breaks first with Backblaze B2?

Cost assumptions when request volume or restore frequency increases. Performance expectations if regions and user geography don’t align. Integration gaps if you rely on hyperscaler-native services and tooling.

What are the hidden constraints of Backblaze B2?

Your workload’s request profile can matter as much as egress for total spend. Restore frequency shifts economics compared to cold storage assumptions. S3-compatibility is helpful, but integration edge cases can still surface.
