Backblaze B2 is the cheapest S3-compatible object store in the 2026 survey: $6 per terabyte-month, with an egress deal that gets very good once Cloudflare is involved. It is the strongest candidate for the Anarchive's offsite media store.
## The Prices
Storage is $0.006 per GB-month. Egress is free up to three times your stored data each month, then $0.01 per GB. Store a terabyte, and three terabytes of monthly downloads cost nothing.
## The Cloudflare Trick
B2 belongs to the Bandwidth Alliance: all egress from B2 that flows through Cloudflare is free, without caps or ratio rules. Put Cloudflare's free CDN tier in front of a public B2 bucket and the result is a $6-per-terabyte archive with unlimited free serving — the pairing Egress Economics recommends for anything popular.
## Fit
S3-compatible API, so `rclone` and every backup tool speaks to it natively. Best role for the Anarchive: the offsite copy of the media assets, and the public origin behind Cloudflare if clips outgrow self-serving.
