pgBackRest retention for both PostgresClusters is **14 days** (`repo1-retention-full` / `repo1-retention-full-type: time` in the base manifests). Schedule is one full backup daily plus hourly incrementals. Older fulls and their dependent incrementals are expired after 14 days.

- Both PostgresClusters (`app-pg`, `temporal-pg`) have their pgBackRest repo volume size patched to `__PG_BACKUP_STORAGE_SIZE__` (default `10Gi`), so test instances can use smaller backup storage
- Backup retention is **14 days** (time-based) with a daily full backup and hourly incrementals (set in the base PostgresCluster manifests, not via env overlay)
