1. A method for excluding disks from an application-consistent backup of an application in a virtual machine comprising:
installing, within the virtual machine, a data protection agent to interact with a copy service of the virtual machine, the copy service comprising a writer that is responsible for freezing the application;
receiving a request to perform the backup, the request including identifications of virtual machine disks (VMDKs) associated with the virtual machine;
communicating with a disk manager of a guest operating system of the virtual machine to generate a map that maps the VMDKs to volumes that are attached to the virtual machine;
communicating with the application to identify which of the volumes contain application databases associated with the application;
notifying the copy service to prepare the application for the backup; and
issuing a request to a snapshot data mover for a snapshot of the application, wherein the request comprises identifications of a subset of the VMDKs mapped to corresponding volumes that contain the application databases, and
wherein VMDKs mapped to corresponding volumes not containing the application databases are excluded from the request.
