- RetentionPolicy (last/daily/weekly/monthly) and PruneService: forget snapshots the policy drops, delete packs nothing uses and repack mostly unused ones by copying encrypted blobs as-is; new packs are indexed before old ones are removed - a location lock keeps prune and backups apart; append-only locations are never pruned (cleanup via the location's lifecycle rules) - weekly prune from the background job; occ backup:prune [--dry-run], backup:retention, backup:target:append-only - tests: forget+prune frees space and the remaining snapshot restores identically, repack of mixed packs, dry-run preview, retention buckets
