- 2. <Insert Picture Here> Agenda • Exa-Backup: Exadata Backup & Restore • Challenges • Data Protection Goals • Best Practice Architectures • Oracle Support Services • Next Steps
- 3. Exa-Backup Backup Options for Exadata Exadata Database Machine Exadata Expansion Oracle Sun StorageTek Tape Library ZFS Storage Appliance (ZFS-SA)
- 4. • Data loss exposure • ESG 2008 estimates that 1 in 7 (14%) backups and 1 in 6 (17%) restores fail.* • Meeting SLA’s • Shrinking backup windows; slow recovery processes • Reducing costs • Reducing both CAPEX & OPEX while improving staff efficiency • Complexity • Complexity of BU&R process and the storage environment • Data growth • Compounding year over year Business Drivers Behind Exa-Backup What keeps our customers awake at night… *Enterprise Strategy Group 2008
- 5. Data Protection Terminology Recovery Point and Recovery Time Objectives Recovery Point Objective Tolerance for data loss (sec’s, hours, days); determines frequency of backups Recovery Time Objective The shorter the Recovery Time Objective (RTO) the quicker you get back to business Data Loss (Recovery Point Objective) Downtime (Recovery Time Objective) Hrs Mins SecsWks Days HrsMinsSecs WksDays Backup Window Static, but needing to accommodate an ever increasing amount of data Value of Data The Business value of data is rarely understood
- 6. Choosing Backup Option Influences • Value of the Data • What is the cost to the company of not getting the data back? This is the true question to be asked • Can some data be restored later and some more quickly? • Will different backup and restore options suit different data categories • Backup Window • How much time is available to backup the data? • With the growth rate of the data how long will the window last • Recovery Time Objective (RTO) • How quickly does the data need to be restored? • Recovery Point Objective (RPO) • To which point in time must the data be restored?
- 7. RMAN • Oracle Recovery Manager (RMAN) is the Oracle-preferred method for efficiently backing up and recovering Oracle databases • Reduces exposure of data loss for Oracle database environments • RMAN backup to disk is preferred over tape because disk provides faster restore • It’s already built into the Oracle Database • Cost Effective, no extra licences to buy • No third party technology to purchase and coordinate • Ensures transaction integrity and manages all information required for database recovery at any point in time • RMAN copies only database blocks that have changed since previous backup • Up to an order of magnitude reduction in backup and recovery times • Significantly improved Recovery Time Objective (RTO) Service Levels
- 8. Exadata Backup (Fastest!) • RTO: Immediate • RPO: Lossless • Customer has the business requirements to support purchase of additional Exadata machine ZFS Storage Appliance Backup (Most Flexible!) • RTO: Next to Immediate • RPO: Last transaction • Customer requires industry leading fast backup and recovery support Tape Backup (Most Economical!) • RTO: Hours • RPO: Last Transaction Backup • Customer requires and economical and green backup and recovery solution Exa-Backup Backup Options for Exadata
- 9. InfiniBand Network Oracle Exadata Storage Cells Oracle Exadata Database Machine Exa-Backup with Exadata Internal or Using additional Storage Cells Highest Performance • Allocate additional 2TB HDD Exadata Storage Servers for a dedicated Fast Recovery Area • Additional Exadata Storage Servers must be installed in another rack • Key Benefits • Better failure isolation when using separate backup hardware • Allows use of lower cost space for backups • Only for data protection • Unbalanced configuration MAA Best Practice
- 10. Sun ZFS Storage Appliance Exa-Backup and ZFS Storage Appliance Most Flexible • Various Connectivity Options • 1 GigE, 10 GigE, IB!! • ZFS works with RMAN to secure against data corruption • RMAN ensures that backups are not corrupt, ZFS ensures they stay that way • Enables dNFS DB Cloning • Leveraging ZFS Storage data services and capabilities • Thin provisioning • Compression • Snapshot and cloning • Replication • Performance Analytics Oracle Exadata Database Machine RMAN
- 11. Oracle Exadata Database Machine • High performance Exadata protection • Scalable – capacity and performance • Simplified data recovery Oracle Secure Backup (OSB) StorageTek Tape Library Exa-Backup to Tape Most Economical Backup Option
- 12. Exa-Backup Putting it all together Exadata Database Machine Oracle Sun StorageTek Tape Library ZFS Storage Appliance (ZFSSA) Exadata Database Machine
- 13. 13 Competition Disk and Tape • ZFS Storage Appliance Beats NetApp and EMC Data Domain! – Over 3x the backup throughput of NetApp FAS3170C – Up to 1.3x the restore throughput of NetApp – Over 3x the backup throughput of Data Domain 880 – Over 3x the restore throughput of DD • ZFS Storage Appliance provides the only direct connect IB connection to Solaris/OEL servers and Exadata! – Save up to $300k in license/support – Take advantage of RMAN features only available via direct connect • Enables direct restore from tape – Faster Restores! • T10000C Beats IBM! – 25% greater capacity, 33% lower TCO, and 50% less floor space than IBM TS1140
- 14. Cost Effective The advantages of a Direct Connection • Direct connect • Leverages Exadata's internally managed InfiniBand network • No network upgrade required • No need for backup app to write to disk • Traditional architectures • Include costly backup applications for backing up to disk • Adds 72% to the 3 year TCO
- 15. Simplicity • Implementation • Already tested, validated, and supported together • Integrated InfiniBand simplifies implementation • Consistent with data center policy/best practices • Data Domain needs full backups to reach 6.3:1 dedupe ratio • Effectively an “incrementals forever” strategy • Full BU’s unnecessarily burden the network • RMAN incremental only back up of changed blocks Stay with current backup and recovery best practices – don’t change
- 16. ZFS STORAGE APPLIANCE Sun ZFS Storage Appliances Independent Study Confirms Simplified Management Source: Edison Group Comparative Management Costs Study, 2010. Faster to provision new storage Faster in administrative tasks Faster to monitor and troubleshoot issues 36%36% 31%
- 17. 17 Ensuring Data Integrity • RMAN corruption detection helps to ensure against corrupt backups. End-to-end ZFS check summing and data integrity ensure the backup stays that way. • Self-healing Fault Management Architecture increase uptime and availability to backups for restores from disk Together with RMAN, ZFS Ensures Against Failed Recovery
- 18. Simplifying Disk-to-Disk-to-Tape • The ZFS Storage Appliance easily connects directly to Exadata’s InfiniBand network - Ensures appropriate restore times without having to go through a media server to disk - Leverages RMAN Toolset - Eliminates extra Media Management Licensing costs • Disk-to-disk-to-tape (D2D2T) allows backup administrators to have the best of both worlds - Keeping off-site backups elsewhere - While retaining fresh backups on disk for ultra-fast restores • Storage hierarchy that balances cost and performance
