Configure VTLs to Function as Arcserve Backup VTLs

Virtual tape libraries (VTLs) are disk-based devices that are designed to behave like physical tape libraries. To allow Arcserve Backup to back up data to these devices, VTLs, you must configure the devices to function as Arcserve Backup VTLs.

Important! You should not configure standard physical libraries to function as an Arcserve Backup VTLs. 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 devices to function as VTLs, verify that the following prerequisite tasks are complete:

• The Tape Library Option is licensed.
• The VTLs are properly configured using Device Configuration.
• Arcserve Backup detects the VTLs.

To configure VTLs to function as Arcserve Backup 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. 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.

   

   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.
