• Data Protection Challenges
• Protecting Data with Oracle Recovery
Manager and Sun Unified Storage Systems
• Best Practice Architectures & Configurations
• Adding Further Value to the Backup
• Sun Support Services
• Next Steps

4. What Keeps Us All Awake At Night
Challenges Brought on By Rampant Data Growth
• Budget
• Need to do more with less
• Management
• Failed back-ups and recoveries
• Completing back-ups within given windows
of time
• Risk
• Reducing exposure to data loss
• Meeting SLAs
• Stringent protection requirements

5. Meeting Recovery SLAs
Quiz
What is your Recovery Point Objective (RPO)?
Minutes?
Hours?
Days?
What is your Recovery Time Objective (RTO)?
Minutes?
Hours?
Days?
(Jobs depend on knowing the answers and delivering on them)

6. First Step in Data Protection Planning
Assess Recovery Requirements
• Identify and prioritize critical data
• Design recovery requirements around data criticality
• Assess tolerance for data loss - Recovery Point Objective (RPO)
• How frequently should backups be taken?
• Point-in-time recovery required?
• Assess tolerance for downtime - Recovery Time Objective (RTO)
• Downtime: Problem identification + recovery planning + systems recovery
• Tiered RTO per level of granularity, e.g. database, tablespace, table, row
• Determine backup retention policy
• Onsite, offsite, long-term
• Assess data protection requirements
• Physical: Disasters, outages, failures, corruptions
• Logical: Human errors, application errors

7. The Power of Backup
Multiple Copies of a logical view taken at specified
points in time allows:
• Recovery from data corruption or data loss
• Meeting Recover Point Objective (RPO) or
Recovery Time Objective (RTO) SLAs
• Maintaining of copies for Disaster Recovery

8. If only Backups were that Simple
• Databases are the most widely deployed and most
challenging application to backup
• Data continues to grow, but back up windows stay the
same or shorten due to 24/7 operation
• Because of this, 1 in 7 backups and 1 in 6 restores fail*
*Enterprise Strategy Group 2008

9. RMAN to the Rescue
• 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

10. Oracle Recovery Manager (RMAN)
Oracle Database Integrated Backup and Recovery
• Intrinsic knowledge of database file formats and
recovery procedures
• Block validation
• Online block-level recovery
• Tablespace/data file recovery
• Online, multi-streamed backup
• Unused block compression
• Native encryption

11. Oracle Recovery Manager
• Simplifies all of the different operations, copies, and
locations of files
• Assists in keeping track of the state of all these various backup
images as well as their locations
• Assists in making the decision that particular backup information
has become obsolete and can therefore be safely retired
• Makes recovery for the DBA much simpler since RMAN keeps track
of all of the files required for recovery operations

12. Sun ZFS Storage Appliance is the Ideal Target
for RMAN Database Backup and Recovery
RMAN and the ZFS Storage Appliance,
a perfect match
Oracle • Cost effective, high
Database performance disk target
RMAN
Disk • ZFS Compression further
Backup shortens backup/recovery
• Relieves Database server CPUs
from doing RMAN Compression
• No extra charge replication
for Disaster Recovery
• Simplify Oracle DR utilizing
replicated copies of RMAN

13. Sun ZFS Storage Appliance
Compression
• ZFS Compression further reduces data to be backed
up and restored
• 2X compression (or 50% space reduction) typical
• Shortens backup/recovery times
• ZFS Compression relieves CPUs on Database
Servers from doing RMAN compression
• Allowing them to focus on more critical tasks

14. ZFS also Further Ensures Against Data
Corruption
Extending SLA compliance with stringent protection
requirements
• End-to-end check summing and data integrity ensure
against corrupt files when restoring old backups
• Self-healing Fault Management Architecture increase
uptime and availability to backups for restores from disk
• Industry leading Triple-Parity RAID further reduces the
risk of data loss

15. Enterprise Disaster Recovery
For all critical Oracle environments, best practice is to
replicate to a secondary recovery location

16. Disk-to-Disk-to-Tape
• Companies are realizing the best data protection
system leverages the strengths of both tape and disk
• The reliability of conventional tape backup combined
with the speed and cost savings of a disk-to-disk
configurations

17. Disk-to-Disk-to-Tape
D2D2T is a tiered storage methodology that combines the
speed of disk with the economy, security and flexibility of tape
• 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
• Automated data movement enabled by 3 rd party
Backup and Recovery applications
