Recovering an Older Version of a vApp
If a vApp has become corrupted, or if users need to revert to an older state of the vApp, the administrator can restore a version of the vApp from backup storage even when the vApp still exists in vCloud Director. The backup/restore application in these cases can access vCloud Director to get vApp identity information and metadata before restoring the backup copy.
The backup/restore application has a choice between overwriting the current vApp instance or deleting it and creating a new vApp. The choice to delete the vApp can be convenient when the vApp configuration has changed since the last backup, especially when a virtual machine has been added to or deleted from the vApp.
