> We changed from ASYNCH to SETALL because it was recommended in the SAP-notes. The time increased so the performance got worse.
With SETALL you bypass filesystem cache therefore performance of backup got worse.
Using Administration Assistant you can view performance data to determine bottlenecks during backup/restore. If only change you performed is SETALL option more likely it is disk i/o related. If it's true (first perform monitoring to be sure) try to tune disk i/o. See official TSM documentation for TDP for SAP.
