1. A method for managing file based backups (FBBs), the method comprising:
obtaining, by a FBB metadata file manager, a FBB mount request for a FBB mount of a FBB from an application, wherein the application is executing in a production host environment, and wherein the FBB comprises file system data comprising data tags and a FBB metadata file;
in response to the FBB mount request, the FBB metadata file manager:
identifies a FBB in a backup storage system;
obtains the FBB metadata file corresponding to the FBB from the backup storage system;
performs an attribute analysis to identify storage location attributes in the FBB metadata file;
stores a FBB virtual file system in the production host environment using the storage location attributes; and
enables access to the FBB virtual file system by the application;
obtaining, from the application, a file request for at least a portion of the file system data stored in the FBB;
in response to the file request:
identifying a storage of the portion of the file system data in the backup storage system via the FBB virtual file system;
initiating generation of a temporary storage device, separate from the backup storage system, that comprises a copy of the portion of the file system data from the backup storage system, wherein the copy does not include data tags; and
initiating access to the temporary storage device by the application.
