  3. 3. 2/17/2012 Agenda• Backup & Recovery Fundamentals• Oracle Backup Tools• Backup Strategies for Exadata 3
  4. 4. 2/17/2012 Business Drivers Behind Backup What keeps our customers awake at night… • Data loss exposure ­ ESG 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.*Enterprise Strategy Group 2008 4
  5. 5. 2/17/2012 Fundamental Data Protection Rule of 3 “3 Copies of the Data on 2 different medias with 1 offsite”• 1st Line of Defense (Applications, Systems) – Typically data deletion, logical corruption or a virus – Look at the RPO. The majority of critical application recovery is likely to come from the snapshot on the same tier of storage• 2nd Line of Defense (Building, Site, Region) – HW failure & Disaster Recovery - failover to a remote site – Circumstances will dictate whether it should be disk and/or tape – Remote disk mirroring provides a physical copy of the data, but does not provide logical data protection (it replicates corruption immediately!)• Last Line of Defense – TAPE! – The last chance to avoid permanent data loss – Data preservation much more important than recovery time 5

  7. 7. 2/17/2012 Flashback Database Fast point-in-time recovery strategy Database Eliminate the need to restore a whole Instance database backup Continuous data protection for database Write Optimized, before-change block logging Restores just changed blocks New Old Replay log to restore DB to desired time Block Block It’s fast - recover in minutes, not hours Version Version It’s easy - single command restore Flashback Database to ‘2:05 PM’`Data Files Flashback Log “Rewind” button for the Database 7
  8. 8. 2/17/2012 Oracle Recovery Manager (RMAN) Oracle-integrated Backup & Recovery Engine • Intimate knowledge of database file Oracle Enterprise Manager formats and recovery procedures • Manages and automates the backup, restore, and recovery policies and process Oracle • Catalog all backup and recovery RMAN Secure activities Backup • Operates online and in parallel for fast processing • Corrupt block detection during backup and restore with the ability Tape Drives to validate backups Fast Recovery Area • Integrated with EnterpriseDatabase Manager, Oracle Secure Backup, and third party backup products 8
  9. 9. 2/17/2012 Oracle Secure Backup (OSB) Enterprise Tape Backup Management Oracle Protects Entire IT Enterprise Manager Environment • Built-in Oracle IntegrationOracle Secure Backup • 25 - 40% faster than Oracle Database File System Data leading competition RMAN Integration • 4 x less expensive than comparable productsTape Virtual • Supports OracleLibrary Tape Library Database 11g through Oracle 9i 9

  11. 11. 2/17/2012Backup Options for ExadataCustomer choice depending upon objectives & budget Exadata Backup (Fastest) • RTO: Immediate • RPO: Lossless • Fastest option using Inifiniband to another Exadata machine ZFS Storage Appliance Backup (Most Flexible) • RTO: Next to Immediate • RPO: Last transaction • Multiple network connectivity & data service options Tape Backup (Most Economical) • RTO: Hours • RPO: Last Transaction Backup • Best economics on cost/GB and offers removable offsite capability 11
  12. 12. 2/17/2012 Exa-Backup with Exadata Using additional Storage Cells - Highest Performance Oracle Exadata Oracle Exadata Database Machine Storage Cells • Requirements for immediate data restore capabilities and reduced backup windows • Primarily data protection against InfiniBand user/logical errors (Flashback) Network • Allocate additional 2TB HDD Exadata Storage Servers for a dedicated Fast Recovery Area Quarter* Half* Full**Backup 8.5 18.5 27.0 • Additional Exadata Storage Servers Rate TB/hr TB/hr TB/hr must be installed in another rackRestore 18.0 28.5 28.5 • External backup still recommended Rate TB/hr TB/hr TB/hr FC * Full Exadata Rack to a Quarter, Half Storage Expansion Rack ** Estimated rate Full Exadata to Full Storage Expansion Rack 12
  13. 13. 2/17/2012 Exa-Backup and ZFS Storage Appliance Most Flexible Oracle Exadata Sun ZFS Storage • Various Connectivity Options Database Machine Appliance ­ 1 GigE, 10 GigE, IB!! RMAN • ZFS works with RMAN to secure against data corruption ­ RMAN ensures that backups are not corrupt, ZFS ensures they stay that way IB / 10Gig E • Enables ZFS Snapshot and RMAN Network incremental backup strategy • Leveraging ZFS Storage data services and capabilities Image Incremental ­ Thin provisioning Copies Backups* ­ Compression ­ Snapshot and cloningBackup Rate 6.5 TB/hr 42.0 TB/hr ­ ReplicationRestore Rate 6.2 TB/hr 7.0 TB/hr ­ Performance Analytics*Effective Rate = Rate * Change Rate Backup = 8.5 TB/hr * 20% Change = 42 TB/hr 13

  16. 16. 2/17/2012Some performance numbersDisk and Tape• Exadata for the most demanding RPO/RTO – Backup up to 18TB/hr (full rack), 20-50TB/hr for incrementals – Restore 18-24 TB/hr (full rack)• ZFS Storage Appliance Beats NetApp and EMC Data Domain! – Over 3x the backup throughput of NetApp – Up to 1.3x the restore throughput of NetApp – Over 3x the backup throughput of Data Domain – Over 3x the restore throughput of Data Domain• T10000C and Oracle Storagetek Libraries beat IBM ! – T1000C 25% greater capacity, 33% lower TCO, and 50% less floor space 16 16
  17. 17. 2/17/2012 Backup and Restore for Exadata Value PropositionSpeed: Complete backups within shorter windows  Faster backup and recovery (flashback and incremental forever RMAN strategy)  Speedy Implementation  Leverages Exadatas internal IB network for extreme performance  Already tested, validated and supported by OracleSimplicity: Avoiding complexity • No third party SW backup to manage required for disk backup • Preserves incremental backups optimizing Database and network performance • ZFS Storage Appliance 30% easier to manage than third party vendorsSavings: Reduced Capex and Opex • Simple architecture reduces costs • No backup and recovery license fees and no media server for disk-based backup • Storage hierarchy that balances cost and performance • T1000C 25% greater capacity, 33% lower TCO, and 50% less floor space 17
