1. A method for managing access to file based backups (FBBs), the method comprising:
obtaining, by a FBB metadata file operating in a production host and from an application, an instant access request for data associated with an FBB, wherein the instant access request is associated with a user, and wherein the FBB is associated with a plurality of users comprising the user and a second user;
in response to the instant access request:
accessing a FBB metadata file associated with the FBB to determine file data that is associated with the user;
performing an attribute analysis on the FBB metadata file to identify a storage location attributes, wherein the storage location attributes are each associated with a storage location of a portion of the file data in a backup storage system;
generating a FBB virtual file system in the production host using the storage location attributes, wherein the FBB virtual file system maps the file data to the storage locations;
enabling access to the FBB virtual file system by the application;
monitoring, after the enabling, the use of the FBB virtual file system;
based on the monitoring, making a determination that a self-destruction criterion has been reached; and
based on the determination, initiating a self-destruction of the FBB virtual file system.
