• 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

Oracle Database

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
