| Storage (entry plan) | 10 GB free, permanently — 'First 10GB storage is always free.' The statement is a row-level note on Backblaze's pricing-model table, so it applies to B2 storage rather than to one plan, and it is an ongoing allowance rather than the 'Start Free' trial the page advertises separately. | 5 GB free, shown against a modelled $1.90 Tigris cost versus $8.75 on AWS and $11.00 on GCS for the same scenario |

DELETE and CANCEL are free. Object notifications cost $0.01 per 1,000 events. |
| Minimum storage duration | None. Backblaze states no minimum file size or storage duration fee on B2 Cloud Storage, so an object deleted an hour after upload is billed only for that hour. | None on Standard. Infrequent Access carries a 30-day minimum; Tigris names Archive and Archive Instant Retrieval as also subject to a minimum, listed in its pricing table as 90 days. Deleting or updating an object sooner is still billed for the full window. |

## Which should you choose?

Pick 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.

Pick 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: 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.

Consider something else: 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.
