S3 has no bucket quota, so NG Backup enforces one: before a pack is uploaded, the stored size plus the pack must stay under the location's limit, otherwise the backup stops with an error (and administrators are notified through the failed run). Repacking during prune is exempt, as it is how space is freed. occ backup:target:limit NAME [SIZE|none]. Also ignore credential files in the repository.
