## Why Servarr backups (periodic config+DB zips) and sonarr MediaCover posters still live on each replica's local `/config` emptyDir: backups are leader-local and lost on reschedule, and sonarr covers render inconsistently across the 3 active-active replicas. #387 moved radarr covers to a shared Ceph RGW bucket; this extends that pattern to backups for all three apps and to sonarr's covers. ## Changes - Add an `arrstack-backups` ObjectStoreUser + Bucket (cephrgw-operator); the operator mints the `arrstack-backups-s3` credential Secret in-namespace (AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / S3_ENDPOINT), so no Vault KV seeding is required. Backups get their own bucket (not `arrstack-media`) because they carry secrets (Config.xml API keys, the DB) and warrant separate credentials/lifecycle from poster art; the three apps share it, isolated by a per-app key prefix. - Wire sonarr to the shared `arrstack-media` bucket via `Sonarr__MediaCoverS3__*` (prefix `sonarr`, partitioned from radarr's `radarr` prefix to avoid movie/series id collisions), plus the estate CA mount at `/etc/ssl/vault-ca/ca.crt` for RGW TLS validation. - Wire radarr/sonarr/prowlarr backups via `<App>__BackupS3__*` to `arrstack-backups` (per-app prefix); add the CA mount to sonarr and prowlarr. ## Notes - Credentials come only from the operator-minted Secret via env; no secrets in manifests. - The env keys are consumed by the -unkin3+ images (separate app PRs) and ignored by older images, so this is safe to apply ahead of the image bump. - `kubectl kustomize apps/base/arrstack` builds clean.
