Agenda • Leveraging Oracle Backups with EMC Data Domain – Applying deduplication in an Oracle environment • EMC Proven Solutions • Results of Three Scenarios Tested – Database on NAS, RMAN backup over NFS to Data Domain – Database on SAN, Net. Worker backup over Fibre Channel to Data Domain • Why EMC Data Domain • Summary © Copyright 2010 EMC Corporation. All rights reserved. 2

Applying Deduplication to Oracle Deduplication enables weeks or months of full backups to be stored in about the same space required for a single backup on traditional disk Without deduplication 1 TB + Week 1 1 TB + Week 2 1 TB + Week 3 With deduplication Initial Full Changed Data © Copyright 2010 EMC Corporation.
