Section 2 - Best practices and recommendations

This section describes the best practices for your backup client application.

2.2 JVM (Java Virtual Machine) memory allocation

For resource intensive backup modules such the following:



• MS Exchange Server backup
• MS VM backup
• MS Windows System backup
• ShadowProtect System backup
• System State backup
• VMware VM backup



If you are experiencing performance issues with the backup application, a common cause is insufficient JVM (Java Virtual Machine) memory allocated for the backup application. The default setting of the maximum heap size is 768 MB.

Consider increasing the JVM (Java Virtual Machine) memory allocation to improve performance of the backup operation.

Note:
The maximum memory allocated should not exceed 70% of the total memory available for the system.

You can increase the maximum heap size of the application by referring to the instruction provided in 1.3 How do I modify the Java heap size of OBM or ACB?
