| 1 | # 🤖 The blob MIRROR bucket (federated blobs Phase A, #992 — |
| 2 | # docs/federated-blob-storage.md): the second copy of every store-backed |
| 3 | # attachment, on the second provider. The PRIMARY blob store is Hetzner |
| 4 | # Object Storage — enabled and credentialed in the Hetzner console, since |
| 5 | # neither the hcloud provider nor this AWS one can manage it; this file is |
| 6 | # the AWS half only. |
| 7 | # |
| 8 | # Versioning is deliberately OFF, unlike the hibernation bucket beside it: |
| 9 | # blobs are write-once (an id is never rewritten, so versions can't help), |
| 10 | # and a delete here is member-initiated GC — retaining a deleted member's |
| 11 | # media as noncurrent versions would quietly betray the deletion. When a |
| 12 | # blob goes, both copies actually go. |
