Agenda
• 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
What Keeps Us All Awake At NightChallenges 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
Meeting Recovery SLAsQuiz
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)
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
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
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
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
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
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
Sun ZFS Storage Appliance is the Ideal Target for RMAN Database Backup and Recovery

Backup
• Cost effective, high performance disk target
• ZFS Compression further 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 backups
RMAN and the ZFS Storage Appliance, a perfect match
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
ZFS also Further Ensures Against Data Corruption
• 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
Extending SLA compliance with stringent protection
requirements
Enterprise Disaster Recovery
For all critical Oracle environments, best practice is to replicate to a secondary recovery location
Multiple copies of the data on disk in separate locations

Disk Backup
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
Disk-to-Disk-to-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 3rd party Backup and Recovery applications
D2D2T is a tiered storage methodology that combines the speed of disk with the economy, security and flexibility of tape
