The NetBackup policy maintains a cache file of virtual machine names. The names are shown in the Browse for Virtual Machines dialog. You can select a virtual machine from the list in the dialog, rather than waiting to rediscover the machines on the network. This approach can save time if your site has a large number of virtual machines.

Discrepancies may exist in the list of virtual machine names. On the policy's Browse for Virtual Machines dialog, click the refresh icon to the right of the Last Update field to update the list of virtual machines.

If you change the virtual machine display name in the Hyper-V Manager, the new name may not be used for backups.
