Sun Unified Storage for Oracle Data Protection
Solution Deployment Scenarios

Business Drivers Behind Exa-Backup
• 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
What keeps our customers awake at night…

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 Point Objective

hours, days); determines
frequency of backups
Recovery Time Objective
The shorter the Recovery Time
Objective (RTO) the quicker you get
back to business

Choosing Backup Option
• 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?
Influences

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

Competition
• ZFS Storage Appliance Beats NetApp and EMC Data Domain!
– Over 3x the backup throughput of NetApp FAS3170C
– Up to 2x the restore throughput of NetApp
– Over 3x the backup throughput of Data Domain 880
– Over 4x 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
Disk and Tape

Cost Effective
• 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
The advantages of a Direct Connection

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

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
