Invalid client error when you restore files using NetBackup BAR interface installed on the virtual machine
If the virtual machine was backed up by display name or UUID, and the display name is not the same as the host name, note: You cannot restore individual files by means of the Backup, Archive, and Restore (BAR) interface if the interface is installed on the virtual machine itself. The files can be restored if BAR is installed on the primary server or media server. In this case, BAR must not be installed on the virtual machine that you want to restore to.
To restore files, the Destination client for restores field in the BAR interface must have a valid host name or IP address.
