ZDLRA is Change-Based (Delta Push) Only captures changes to data Oracle DBMS (any DBMS) tracks and manages changes to data ZDLRA taps into these mechanisms De-Duplication looks for Un-Changed data Generic technology works on ANY data (works better with non-database data) Attempts to identify and discard data that has NOT changed Not very accurate, only identifies a portion of the un-changed data Depends on disabling Oracle DB (RMAN) performance features 41

Summary Most efficient backup/recovery possible Minimal processing impact on PRODUCTION storage, SAN, servers, WAN Use system resources for transacting business, not running backups Provides validated recoverability Never worry again about recoverability of backups (compliance/audit reports) Real-Time view to recoverability status (mitigate risk, peace of mind) Fully automated & simplified backup/recovery Simplified deployment (no agents), administration, and operation (RMAN, OEM) Fewer resources to manage faster backup, recovery, migrations (faster time to value) Very cost effective solution Lower cost from greater efficiencies (people, process, technology) Oracle Confidential Highly Restricted 44
