Hi Ruud, in the ADSM-L archives you will find a thread about backing up to disk or tape. The recommandation was to backup SAP R/3 directly to tape because you could use more drives, keep the tapes streaming and avoid disk latency. See thread: "Backup faster to tape than disk"
Do you use caching on your disk storagepools?
