AbstractIBM Tivoli Storage Manager (TSM) provides a variety of application integrated solutions.This presentation covers the mySAP environment with

TSM for ERP which supports tape backup to the TSM serverand TSM for Hardware which exploits the FlashCopy function of the EnterpriseStorage Server (ESS) FlashCopy Solutions

This presentation shows the added-values of our solutions and their evolution gated byevolving customer requirements and covers the following topics- positioning of Tape Backup using

Data Protection for mySAP (TSM for ERP)- the evolution to new techniques, mainly FlashCopy- positioning of FlashCopy Solutions based on

DP for ESS for mySAP (TSM for Hardware)

Techniques Observations

Tape backup techniques have maturedrestauration windows will increase caused by DB growth

Increased usage of disk as backup storage mediaprice reduction

Replication techniques to shorten intervals betweenbackups

increased differential (less additional capacity and time tocopy)

FlashCopy and Snapshotmove towards Volume Manager?

'zero impact' Backupmoves backup load from production to backupserverenables snapshots of data 'on demand', any timeshifts tape usage to low activity periodsminimizes online backup window on DB (duringFlashCopy only) fewer logs -> shorter recovery

'minute' Restoreeliminates data transfers from tapes by FlashCopy ofbackups on disk (w/ or w/o additional tape backup)forward recovery can start directly after (reverse)FlashCopy is establishedreduces restore time from hours to minutes
