1. A method for performing data protection of file system data on a host, comprising:
identifying, by a data protection agent, a backup access event associated with a backup of a file system, wherein a first portion of the backup is stored on a first backup storage and a second portion of the backup is stored on a second backup storage;
in response to identifying the backup access event:
obtaining backup metadata associated with the backup from a data protection manager;
generating a placeholder file structure using the backup metadata and storing the placeholder file structure in a virtual hard disk file; and
performing heterogeneous backup storage backup access services using the placeholder file structure and the backup metadata to facilitate transfer of data of the first portion of the backup on the first backup storage and the transfer of data of the second portion of the backup on the second backup storage to an application associated with the backup.
