Any time data on a machine is backed up, information about the machine name, operating system, Windows service pack and security identifier (SID) is added to the backup, along with the user-defined text label. The label may include the department or machine owner's name or similar information that can be used as a tag or a key.
If you recover the machine to a VMware ESX(i) using Agent for ESX(i), or convert the backup to a ESX(i) virtual machine, these properties will be transferred to the virtual machine's configuration. You can view them in the virtual machine settings: Edit settings > Options > Advanced > General > Configuration parameters. You can select, sort and group the virtual machines with the help of these custom parameters. This can be useful in various scenarios.
Example:
Let's assume you migrate your office or datacenter to a virtual environment. By using third-party software that can access configuration parameters through VMware API, you can automatically apply security policies to each machine even before powering it on.
