Setup guides
Breazzy speaks the standard S3 protocol, so it works with any S3-compatible provider. Pick the one that fits your budget and location — the setup process is the same four fields in every case: endpoint, access key, secret key, and bucket name.

Which provider should I pick?
For most people: Backblaze B2. It is the cheapest fully-supported option with a generous free tier and straightforward pricing. The B2 setup guide is the most tested path.
If you re-download a lot: Cloudflare R2. Zero egress fees with no monthly cap. Slightly more expensive for storage but free to retrieve. See the R2 setup guide.
If you want the absolute lowest price: iDrive e2. At $2.49/TB it is roughly 2.4× cheaper than B2. The setup is slightly trickier (account-specific endpoint URL) but well worth it for large libraries. See the iDrive e2 guide.
