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 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

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

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

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
