Backblaze B2 vs Tigris
SEPT 2026 auditA comparison of Backblaze B2 and Tigris built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose Backblaze B2 if…
Bulk capacity where egress is predictable — free up to three times what you store each month, which covers most backup and archive patterns comfortably at $6.95 per terabyte.
Editorial · Palash Bagchi · approved
Choose Tigris if…
Globally distributed buckets with no egress fees and tiered storage, where cold data drops to $0.004 per GB-month without a separate archive product to manage.

Consider something else if…
- Backblaze B2: Egress is only free to that 3x ceiling. A bucket read far more often than its size, like a public media library, is the shape this pricing is not built for.
- Tigris: Retrieval is charged on the Infrequent Access and Glacier tiers, so the tiering that lowers the storage bill can raise the access one. The cheapest tier is not the cheapest for data you actually read.
