improve performance in your specific environment and determine the optimum asynchronous reading settings.
SAN performance
If large volumes of data need to be backed up in one session, the time needed to transfer the data becomes significant. This consists of the time required to move the data over a connection (LAN, local, or SAN) to a backup device.
Online database application performance
When you back up databases and applications, such as Oracle, SAP R/3, Sybase, and Informix Server, the performance of the backups also depends on the applications. Database online backups are provided so that backups can occur while the database application remains online. This helps to maximize database up time but may impact application performance. Data Protector integrates with all popular online database applications to optimize backup performance.
For more information on how Data Protector integrates with various applications and for tips on how to improve backup performance, see the HP Data Protector integration guide.
Also see the documentation that comes with your online database application for more information on how to improve backup performance.
Planning security
When you plan your backup environment, consider security. A well thought out, implemented, and updated security plan prevents the unauthorized access, duplication, or modification of data.
What is security?
Security in the backup context typically refers to:
•Who can administer or operate a backup application (Data Protector).
•Who can physically access client systems and backup media.
•Who can restore data.
•Who can view information about backed up data.
Data Protector provides security solutions on all these levels.
