The Tape Engine is an Arcserve Backup component that controls all jobs that involve backing up, restoring, and recovering data. In large backup environments, the following conditions can have adverse affects on Tape Engine performance:
Diminished Tape Engine performance can occur due to the amount of virtual memory that is allocated to applications by the operating system. By default, Windows 32-bit operating systems allocate 2 GB of virtual memory for applications. The default allocation on 32-bit operating systems can prevent computers that contain 3 or more GB RAM from utilizing all of the RAM that is installed on the computer.
Note: Windows 64-bit operating systems can allocate up to 4 GB of virtual memory.
Windows operating systems let you increase the amount of virtual memory allocated for applications. If your backup server demonstrates slow performance in a large backup environment, you can increase the amount of virtual memory available to applications to improve the performance of the Tape Engine.
Note: You should increase virtual memory only of your backup server contains a Windows 32-bit operating system with at least 2.5 GB RAM.
The following sections describe how to increase virtual memory allocation on computers running 32-bit versions of Windows Server 2003 and Windows Server 2008.
To increase virtual memory allocation on 32-bit Windows Server 2003 systems
