6 Key Database Protection Goals Business Goals Never lose critical business data No impact on business applications I.T. Goals Ensure database level recoverability Centralized service to protect all databases Current backup appliances fail to achieve these goals 6

7 Backup Appliances Are Not Designed for Database Treat Databases as Just Files to Periodically Copy Data Loss Exposure Lose all data since last backup Daily Backup Window Large performance impact on production Poor Database Recoverability Many files are copied but protection state of database is unknown Many Systems to Manage Scale by deploying more backup appliances 7

8 Data Protection: Still A Complex Task Backups are too slow Significant challenges for data protection? #1: Backing up and managing increasingly large data volumes Backups need constant management Complex Recovery Production slow down Coordination of multiple backups Ref. Oracle Database And Data Protection Survey (200 IT professionals), January

9 Need a Fundamentally Different Approach to Protect Business Critical Database Data Zero Data Loss Recovery Appliance 9

10 Agenda Data Protection: Current State Zero Data Loss Recovery Appliance Configuration Complementary Solutions Ressourcen 10

11 Recovery Appliance: Unique Benefits for Business and I.T. Eliminate Data Loss Real-time redo transport provides instant protection of new transactions Minimal Impact Backups Production databases only send changes. All backup and tape processing offloaded Database Level Recoverability End-to-end reliability, visibility, and control of databases, not disjoint files Cloud-Scale Protection Easily protect all databases in the data center using massively scalable service 11

12 Zero Data Loss Recovery Appliance Overview Protected Databases Delta Push Recovery Appliance Offloads Tape Backup DBs access and send only changes Minimal impact on production Data Guard-like real-time redo ship instantly protects new transactions Protects all DBs in Data Center Petabytes of data, any DB release No expensive DB backup agents Delta Store Stores validated, compressed DB changes on disk Fast restores to any point-in-time using deltas Built on Exadata scaling and resilience Enterprise Manager end-to-end control Replicates to Remote Recovery Appliance 12

13 Recovery Appliance: Fundamentally Different Approach Eliminate Data Loss Real-time redo transport provides instant protection of new transactions Minimal Impact Backups Production databases only send changes. All backup and tape processing offloaded Database Level Recoverability End-to-end reliability, visibility, and control of databases, not disjoint files Cloud-Scale Protection Easily protect all databases in the data center using massively scalable service 13

14 Data Guard Like Data Protection for all Databases Protected Databases Generic Bit-Copy Backup Appliance Backup taken once a day Data loss exposure: all transactions since last backup Zero Data Loss Recovery Appliance Uses Data Guard continuous real-time redo transport from in-memory buffers to immediately protect new transactions Data loss is inherently bad. Even worse..it creates massive consistency issues across databases 14

15 Data Loss Protection from Site Disasters Local Data Center Remote Data Center One Way Bi- Directional Hub & Spoke Tape Library Replication to Remote Appliance protects data from disasters or site failures Automated restore from Local Appliance or directly from Remote Appliance 15

16 Data Loss Protection from Users or Errors Autonomous Tape Archival 16Gb FC Supports Most Major Tape Libraries Optional low-cost Tape Archival provides unalterable protection from: Intentional attacks by hackers, employees, and viruses Accidental data deletion using tape as long-term archive Malfunction of primary data protection system Autonomous Tape Archival is built-in: just connect tape drives Offloads tape backup activity from production servers No expensive media manager backup agents on production systems Tape drives run all day without slowing production systems Oracle Secure Backup included, or use your own tape software 16

17 Data Loss Protection from Corruptions Recovery Appliance Understands and Validates Database Formats End-to-end Data validated on receive Data periodically revalidated Data validated on restore Production Appliance Tape Archive Remote Replica Data validated when copied to and restored from tape Data validated on receive, restore, and periodically 17

18 Recovery Appliance: Fundamentally Different Approach Eliminate Data Loss Real-time redo transport provides instant protection of new transactions Minimal Impact Backups Production databases only send changes. All backup and tape processing offloaded Database Level Recoverability End-to-end reliability, visibility, and control of databases, not disjoint files Cloud-Scale Protection Easily protect all databases in the data center using massively scalable service 18

19 Delta-Only Architecture No More Full Backups: Database Optimized Incremental-Forever Protected Database Compressed Delta Store Change Data No more full backups, only changes Delta Push Disaster Recovery Delta Push Source Deduplication Fast Incremental Backup - Never reads duplicate blocks - Never sends duplicate blocks Eliminates Undo Blocks for committed transactions Eliminates Unused Blocks Delta Store Backup Management Stores only change data Compresses at block-level Ships only Deltas to Replica Dramatic Database I/O & Network Savings 19

20 Space-Efficient Virtual Full Backups No More Full Backups: Incrementals Forever Architecture Day N Virtual Full Day 1 Virtual Full Day 0 Full Day 1 Incr Day N Incr After one-time full backup, incrementals used to create virtual full database backups on a daily basis Pointer-based representation of physical full backup as of incremental backup time Virtual backups typically 10x space efficient Enables long backup history to be kept with the smallest possible space consumption Protected Databases Delta Store Time Machine for database 20

21 Fast Restore to Any Point-in-Time No Load On Production Servers to Merge Old Backups RESTORE DATABASE TO DAY N Protected Database Day 0 Full Day N Full Backup Day 1 Incr Delta Store Day N Incr Directly restore any virtual full backup All blocks referenced from virtual full are efficiently retrieved Eliminates production server overhead of traditional restore and merge of incrementals Supported by the scalability and performance of the underlying Exadata hardware architecture 21

22 Minimal Impact Backups: Boost Production Server Performance Offload Backup Processing, Eliminate Expensive Backup Agents, Reduce Network Load Performance degrades with backups Performance improves with backup offload Disk / Tape / Dedupe Backup Agents Disk / Tape / Dedupe Backup Agents Backup Operations: Merge, Compress, Validate, Delete, Full/Tape Backups Backup Operations: Merge, Compress, Validate, Delete, Full/Tape Backups Delta Push Database Server Today Database Server with Recovery Appliance 22

23 Recovery Appliance: Fundamentally Different Approach Eliminate Data Loss Real-time redo transport provides instant protection of new transactions Minimal Impact Backups Production databases only send changes. All backup and tape processing offloaded Database Level Recoverability End-to-end reliability, visibility, and control of databases, not disjoint files Cloud-Scale Protection Easily protect all databases in the data center using massively scalable service 23

30 Policy-Based Database Protection as a Service Gold Policy Customer Critical Disk: 45 days Tape: 90 days Silver Policy Internal Critical Bronze Policy - Test/Dev Disk: 30 days Tape: 45 days Disk: 15 days Tape: 30 days Tape Replica Replica Recovery Appliance also policy-based Recovery Appliance Protection Policies Standardized recovery window, tape retention, replication policies 30

31 Dynamic Policy-Based Space Allocation Sales DB Web DB Recovery Window Goals Sales Web Space dynamically reallocated between databases to meet recovery window goals E.g. recover to any time in the last 30 days Avoids storage islands and overallocation typical of host or LUN oriented provisioning 31
