The Need
Key Customer Concerns
Continuous availability (24x7) of
mission-critical Oracle databases
• How much does downtime cost your business in
regard to lost user productivity, reduced company
revenue, and poor customer service?
Faster access to data
• Are you using file systems or raw disk partitions
to store Oracle data?
Easier management of increasing data
• Do your DBAs have to learn how to manage raw
disk partitions to gain database performance?

New Feature Overview
Support for Asynchronous I/O
• Raw device performance
• Up to 160% faster than buffered I/O file systems
• Allows for parallel updates to datafiles
Storage Checkpoints
• Enable Block-Level Incremental Backup
• Enable Storage Rollback for immediate “point-intime” recovery from on-disk images
Key Differentiator:
VERITAS Storage Checkpoints
Point-in-time snapshot of database
Storage Checkpoints maintain changed
data blocks as database is being
updated
• Uses efficient copy-on-write technique
• No post-processing needed to scan for
changed data blocks
Benefits of Storage Checkpoints
Storage Rollback:
• VxDBA utility manages Storage
Checkpoints for faster database
recoverability from on-disk backup image
• Protects from logical errors
• What-if analysis
Block-Level Incremental Backup:
• NetBackup manages Storage Checkpoints
and extracts only the changed blocks
• Virtually eliminates database backup
window
Storage Rollback
Storage Checkpoints are on-disk backup
images
• Consistent, stable images of a file system at a
particular point in time
Storage Rollback is “restore” from the ondisk backup images or Storage
Checkpoints
• Copies before-images of data blocks back to the
live file system
• Restores without going to tapes
Storage Rollback
Recovery from Storage Checkpoints
=
Simply write back changed (blue) blocks
to previous state and then apply redo logs
to bring database to desired point in time
Block-Level Incremental Backup
Back up only changed data blocks!
Increased data availability
• Virtually eliminates database backup windows
• Allows more frequent backup schedules
Backups contains up-to-date data
Enhanced performance
• Significantly lowers CPU and network resource drain
during backup
• Faster recovery from backups (less redo logs to apply)
Requires NetBackup Server engine and
database server to be backed up to be a
NetBackup client
