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 solutions fail to achieve these goals

2


Backup Technology Evolution

Industry focus on Optimization of Storage Capacity, not on Application Availability

1980’s 1990’s Early 2000’s 2010’s

Tape Libraries

Network Attached Storage

Virtual Tape Libraries (VTLs)

Deduplication

Late 2000’s

Purpose-built Backup Appliances (PBBAs)

3


Backup Appliances Are Not Designed for Database Treat Databases as Just Files to Periodically Copy

Daily Backup Window

Large performance impact on production

Data Loss Exposure

Lose all data since last backup

Many Systems to Manage

Scale by deploying more backup appliances

Poor Database Recoverability

Many files are copied but protection state of database is unknown

4


Data Protection: Still A Complex Task

• Significant challenges for data protection?

• #1: Backing up and managing increasingly large data volumes

Ref. Oracle Database And Data Protection Survey (200 IT professionals), January 2014 http://www.dbta.com/DBTA-Downloads/ResearchReports/Oracle-Database-and-Data-Protection-Survey-Results-4331.pdf

Backups are too slow

Backups need constant management

Complex Recovery

Production slow down

Coordination of multiple backups

5


Zero Data Loss Recovery Appliance

Need a Fundamentally Different Approach to Protect Business Critical Database Data

6


Recovery Appliance Unique Benefits for Business and I.T.

Minimal Impact Backups

Production databases only send changes. All backup and tape processing offloaded

Eliminate Data Loss

Real-time redo transport provides instant protection of ongoing transactions

Cloud-Scale Protection

Easily protect all databases in the data center using massively scalable service

Database Level Recoverability

End-to-end reliability, visibility, and control of databases - not disjoint files

Zero Data Loss Recovery Appliance Overview

Delta Push

•DBs access and send only changes • Minimal impact on production

•Real-time redo transport instantly protects ongoing transactions

Protected Databases

Protects all DBs in Data Center

•Petabytes of data •Oracle 10.2-12c, any platform •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

Recovery Appliance

Replicates to Remote Recovery Appliance

Offloads Tape Backup

Recovery Appliance: Data Guard Like Protection for all Databases

Generic Bit-Copy Backup Appliance

• Backup taken once a day • Data loss exposure: all transactions since last backup


• Uses Data Guard continuous real-time redo transport from in-memory buffers to immediately protect ongoing transactions

Protected Databases

Data loss is inherently bad. Even worse..it creates massive consistency issues across databases

Full Backups + Incrementals

Redo blocks + Incrementals


Delta-Only Architecture No More Full Backups: Database Optimized Incremental-Forever

Delta Push

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

Protected Database Compressed Delta Store

Dramatic Database I/O & Network Savings

Change Data

No more full backups, only changes

Disaster Recovery

Space-Efficient “Virtual” Full Backups

• 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

• “Time Machine” for database Delta Store

No More Full Backups: Incrementals Forever Architecture

11


Fast Restore to Any Point-in-Time No Load On Production Servers to Merge Old Backups

• 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 Delta Store Protected

Gained validated backup

confidence

CUSTOMER PERSPECTIVE

ZDLRA has also introduced faster recovery times so now we’re able to recover and restore in a matter of 2 to 4 hours instead of previously where we had an average of about 20 hours of restore time.

$850M a month in payments processed

without data loss

13X faster backup performance

65% capacity savings

over Data Domain

CUSTOMER PERSPECTIVE

We selected Oracle’s Zero Data Loss Recovery Appliance over Data Domain because only Oracle could offer the incremental-forever backup feature, enabling us to virtually eliminate data loss exposure and ensure data security.
