Configure Libraries to Function as VTLs

Read performance improves when you configure a library to function as a virtual tape library (VTL). This capability lets CA ARCserve Backup maximize drive efficiency and overall VTL backup and data migration performance.

Important! You should not configure a physical library to function as a VTL. The library's backup and data migration performance can be adversely affected when configured to function as a VTL.

• Prerequisite Tasks

Before you can configure libraries to function as VTLs, ensure the following prerequisite tasks are complete:

• Ensure that the Tape Library Option is licensed.
• Ensure that the VTLs are properly configured using Device Configuration.
• Ensure that CA ARCserve Backup detects the VTLs.

To configure libraries to function as VTLs

1. From the Administration menu in the Navigation Bar on the Home Page, select Device.

   The Device Manager window opens.

2. From the Server directory tree, locate the VTL.

   Right-click the VTL and select Library Properties from the pop-up menu.

   The Library Properties dialog opens.

3. Select the General tab.

   In the VTL (Virtual Tape Library) section, check the Library is a VTL check box and click OK. CA ARCserve Backup ignores specified media expiration dates when you select this option.

   The library is identified as a VTL in the Backup Manager, Destination tab as illustrated by the following screen:

   

   Note: If you do not want to identify a library as a VTL, repeat the above steps and remove the check mark from the Library is a VTL check box.
