Data Protection Challenges for Oracle

1) Disk and Tape Capacity required to store many copies of

Oracle backups

2) Bandwidth required to move large database backups

across WAN for Disaster Recovery

3) Oracle database recovery operations demand extremely

reliable disk storage let alone countless tape media

4) Integration and management of RMAN and backup

infrastructure


EMC BRS for Oracle Data Protection

1) Deduplication Enables Online Retention– Efficiently store weeks of backups on disk for rapid database

restores

– Reduce dependence on tape for Oracle data protection

2) Replication Drives WAN-efficient Disaster Recovery– Time-to-DR minimized, enabling offsite recovery of databases

3) Data Invulnerability Architecture Ensures Reliable Recovery– Provides much higher levels of hardware and software protection

than conventional tape, RAID and file systems

4) Flexible Integration with Oracle– Provides multiple interface options (NAS, Boost, VTL) for use

with Oracle data-protection best practices

Data Domain for Oracle RMANBoost versus NFS/dNFS

Consider RMAN with Data Domain Boost when:– Full backups are recommended;

especially w/ high change rate *

– Time to scan entire database is not a concern

– NFS security or mount point failure is a concern

– RMAN managed DR is a requirement

– Oracle 10g and 11g environments

Consider RMAN via NFS/dNFS with Data Domain when:– Incremental merge is preferred

when change rate is low *

– Time to scan entire database is a concern

– Network link failure is rare or job restart is acceptable

– Backup/Restore is the only requirement; DR is not

– When the environment is Oracle 11g with dNFS

* Oracle recommends full if incremental is more than 20%

DBA’s have complete control over their own Database Backups & Recoveries and with a greater number of backup copies stored


The EMC BRS, RMAN Catalog Assessment

Engage with your local EMC BRS Systems Engineer to better understand the health and statistics of your Oracle backups

Identify slow database backups and frequent failures

Helps to provide sizing inputs to accurately size a new Oracle tape free backup solution

– Size of 1 day’s full backup across all databases– Size of 1 day’s archive log backups across all databases– Identify daily change rate

Identify whether compression and/or encryption are in use


A happy customer…

“Thanks to Data Domain, backup performance has been significantly enhanced, while data storage requirements

have been reduced by 96 percent…The DBAs have control of their backups and they are very happy with that.”

Nancy MagersAssociate Director for Disaster Recovery

Brown University


and another happy customer…

“In a private cloud, you have to look at the storage and backup as hand in glove because of the shared infrastructure. With EMC

Data Domain, its been a seamless process to integrate backup with our virtualized infrastructure. We haven’t had a single

issue, and our Oracle backups and restores are so much faster and easier to manage.”

Oracle dNFS (Direct Network File System)• New in Oracle 11g• To enable, you must still NFS mount

the remote storage on NAS or Data Domain (using OS).• Oracle configuration files tell Oracle

database to manage NFS read/write via Oracle kernel rather than operating system.• dNFS aggregates NIC cards with no

OS config needed. Great performance.
