Backup Tuning

You may experience performance problems during backup operations on computers running Windows Server 2003. This problem occurs because of the way that the Jet database cache size increases or decreases depending on the Transition Fault/sec counter from the operating system. For example, currently backup is performed by using the cache, which affects the Transition Fault/sec counter. This example may cause inconsistencies in how the Jet database memory management feature optimizes its memory usage and in how it tries to free more memory for the operating system.

You can modify the attribute to improve backup performance. This setting also resolves performance issues related to context indexing. For detailed instructions, see How to Set the msExchESEParamCacheSizeMin Attribute.
