wherein the DPM is a second CD that comprises at least second integrated circuitry to perform second computer implemented services for the user,

wherein the file system is at least one selected from a group consisting of a new technology file system, a resilient file system, and an extended file system, wherein the BBB uses a virtual hard disk file format;

obtaining, using the MBB mechanism, a second modified file system metadata from a second snapshot of the file system, wherein the snapshot is generated at a first point in time and the second snapshot is generated at a second point in time;

comparing the modified file system metadata and the second modified file system metadata to obtain a list of changed assets;

initiating an incremental backup of the list of changed assets, wherein the list of changed assets is backed up using a file-based backup (FBB) mechanism, wherein the FBB mechanism implements a multi-stream incremental backup to back up the list of changed assets; and

generating a synthetic full backup by combining the full backup and the incremental backup.

analyzing the second modified file system metadata to generate an index for each asset of the file system;

reordering the index of each asset to generate a reordered index, wherein the reordered index reflects a file system hierarchy of the file system;

determining a user access level of a user;

identifying assets in the reordered index to obtain a set of permitted assets for the user, wherein the user can only access to the set of permitted assets based on the user access level;

providing a graphical user interface (GUI) specifying the set of permitted assets;

receiving selected assets among the set of permitted assets via the GUI; and

restoring the selected assets from the synthetic full backup.

obtaining, using the MBB mechanism, a second modified file system metadata from a second snapshot of the file system, wherein the snapshot is generated at a first point in time and the second snapshot is generated at a second point in time;

comparing the modified file system metadata and the second modified file system metadata to obtain a list of changed assets;

initiating an incremental backup of the list of changed assets, wherein the list of changed assets is backed up using a file-based backup (FBB) mechanism, wherein the FBB mechanism implements a multi-stream incremental backup to back up the list of changed assets; and

generating a synthetic full backup by combining the full backup and the incremental backup.

9. The non-transitory computer readable medium of claim 8 , further comprising:
