1. A method for generating a backup of a virtual machine, the method comprising:

  • creating, by a processor, a virtual machine disk with a plurality of partitions in a datastore;

    creating at least one partition of the plurality of partitions as a read-only partition and at least another partition of the plurality of partitions as a read-write partition;

    loading, by the processor, a software application in the read-only partition of the virtual machine disk, the software application being configured to collect metadata relating to at least one application executing in an operating system of the virtual machine;

    communicatively coupling the datastore to the virtual machine;

    collecting, by the software application, the metadata relating to the at least one application executing in the operating system of the virtual machine and storing the metadata in a portion of the read-write partition, in order to facilitate recovery of the at least one application from a backup archive;

    generating a snapshot of the virtual machine;

    performing post-snapshot operations on the snapshot; and

    storing, by the processor, a backup of the virtual machine in the backup archive based on the snapshot.
