4 Problems with Generic Backup Solutions Designed for Flat File Backups and NOT Transactional Databases Always on Low Results Backup Windows Often Not Met Data Loss Exposure Unacceptable for Critical Databases No Insight Into Recovery Unknown State of Data Protection Minimal Deduplication Ratios Lack of Oracle Database Deduplication Capability Babysitting Backups! Appliance Sprawl No Scale-out: Increases Complexities No Alerts on Recovery Alerts Focused on Just Backups Slow Restore Performance Most Only Publish Backup Speeds Overhead and More Overhead Full Backups, Purging, Deduplication, Validation etc 4

41 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

42 From Base Rack to 18 Racks Wide Base Rack 2x Compute Servers with high speed connectivity * Eight 10 Gb Ethernet ports per rack Twelve 40 Gb InfiniBand ports per rack Optional Four 16 Gb Fibre Channel ports for tape connectivity Extra Storage Recovery Appliance Base Rack 3x Storage Servers * Each storage server has 12 high capacity disks Customers choose number of additional storage servers at purchase or later to increase capacity Full Rack: 2x Compute Servers, 18x Storage Servers Fully Redundant * Ref.

43 Recovery Appliance Scaling Performance per Full Rack Up to 120 TB/hour Virtual Backup Rate Up to 12 TB/hour Sustained Delta Ingest Up to 12 TB/hour Restore Rate Add InfiniBand connected racks to scale Can expand with new generation hardware Scale to 18 Racks Up to 216 TB/hour Delta Ingest and Restore 43

44 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
