RecoverPoint Continuous Data Protection (CDP) RecoverPoint splitter drivers –Mirrors server writes to RecoverPoint appliance –Resides on host or in fabric RecoverPoint appliance –Managed and prioritizes resources –Writes changes to local CDP Journal –Distributes changes to target Journal –Tracks all data changes to every protected LUN –Utilizes bookmarks for application-aware recovery –Repository for live data updates –Provisioned from existing SAN LUNs –Dynamically compressed, which saves storage Supports heterogeneous environments –RecoverPoint supports EMC and third-party storage* –RecoverPoint/SE supports CLARiiON arrays only Application servers Database servers Messaging servers File and Print servers Disk systems Local CDP Journal EMC Third- Party * Support for third-party storage requires intelligent fabric SAN

RecoverPoint Continuous Remote Replication (CRR) RecoverPoint splitter drivers –Intercepts server writes (block level) –Resides on host, CLARiiON, or in fabric* –Mirrors write to RecoverPoint appliance RecoverPoint appliance –Bandwidth reduction with data compression for WAN transfer –Distributes changes to remote site –Supports instant access to protected data Journal –Tracks all data changes to every protected LUN –Utilizes bookmarks for application-aware recovery –Dynamically compressed, which saves storage Provides advanced functionality –Policy-based bandwidth management –5–10 times bandwidth reduction –Replicate over IP or Fibre Channel Supports heterogeneous environments –RecoverPoint supports EMC and third-party storage* –RecoverPoint/SE supports CLARiiON arrays only EMC Third- Party EMC Third- Party SAN or WAN * Support for third-party storage requires intelligent fabric SAN

Journaling for Application-Aware Recovery Time/date –Identifies the time image was saved Bookmarks: –System-generated group bookmarks e.g., Volume Shadowcopy Service (VSS) backup –User-generated bookmarks –Other EMC product bookmarks EMC Replication Manager –System-event-generated bookmarks –Microsoft SQL Server Microsoft Virtual Device Interface (VDI) operations –Microsoft Exchange Microsoft VSS Journal Includes Data Plus Metadata

RecoverPoint Recovery Process Request image via management interface User selects by bookmark or point in time RecoverPoint recovers image as read/write –User chooses virtual or physical target –Existing Journal data used to play back changes to appropriate bookmark or point in time –Target-mounted read/write to recovery server All new writes saved in Journal –Existing disaster-recovery protection not impacted –Image changes committed on request Recovery-image use cases –Failover production to image –Start new application from image –Surgically repair data from image –Fast production resynchronization Rollback production from changed blocks –Source for backup –Data analysis –Disaster-recovery development and testing (fire drill) Recovery request Target volumes History Journal RecoverPoint appliance Servers at recovery site v SAN

Understanding Data Consistency Applications and data are interrelated (Federated) All data movement must be stopped/started at the same point in time To restart applications you must have all the datanot parts of it Recovery requires dependent- write consistency across all volumes and systems Systems share information…how do you get a consistent view? Order Entry SCM CRM DB

16 16 © Copyright 2009 EMC Corporation. All rights reserved. Grouping for a Consistent View Allows application recovery to be tiered by service level –Multiple volumes per group –Mixed recovery point objectives within same infrastructure Provides independent replication controls –Recover by group, locally or remotely –Start/stop by group Enables grouping of optimization –Importance –Resource usage –Recovery point and recovery time objectives Group 3 Group 1 Group 2 E-mailCRR CDPSCM CRROE CRR CRM CDP
