Data Protection in SAP Environments

Arnold Erbslöh Tivoli Storage Manager Development erbsloeh@de.ibm.com

Abstract

IBM 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 server and TSM for Hardware which exploits the FlashCopy function of the Enterprise Storage Server (ESS) FlashCopy Solutions This presentation shows the added-values of our solutions and their evolution gated by evolving 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 matured restauration windows will increase caused by DB growth Increased usage of disk as backup storage media price reduction Replication techniques to shorten intervals between backups increased differential (less additional capacity and time to copy) FlashCopy and Snapshot move towards Volume Manager?

FlashCopy Effective 'Instant Copy' process issue command when copy is needed source and target volumes are immediately available, each with r/w access with nocopy option physical copy is generated only if source data change Incremental FC only copies changed blocks multiple FlashCopy volumes can be maintained target volumes can be used for alternate processing

FlashCopy Backup/Restore 'zero impact' Backup moves backup load from production to backup server enables snapshots of data 'on demand', any time shifts tape usage to low activity periods minimizes online backup window on DB (during FlashCopy only) fewer logs -> shorter recovery 'minute' Restore eliminates data transfers from tapes by FlashCopy of backups on disk (w/ or w/o additional tape backup) forward recovery can start directly after (reverse) FlashCopy is established reduces restore time from hours to minutes

24 IBM Software Group | Tivoli software

FlashCopy Cloning on demand Cloning no intermediate backup necessary 'zero' impact on production system (on-/offline cloning) short time to activate clone customizable options through parameter selection complete support for overall process

SAP Certification

As a result of our cooperative work with SAP on Copy Backup:

Tivoli Storage Manager for Hardware is first to certifiy to BC-BRS interface

29 IBM Software Group | Tivoli software

SAP-IBM Integration Assessment, Aug. 2002 In order to ensure that customers get trusted solutions for backup and recovery of their vital mySAP data, IBM and SAP AG conducted an Integration Assessment of IBM‘s FlashCopy Solutions for DB2 UDB and Oracle databases.

This assessment strengthens Tivoli Storage Manager‘s leading position in the SAP R/3 storage management area.
