1. A method for protecting data in a storage system, the storage system comprising a management server, a media management component connected to the management server, at least one Network-Attached Storage (NAS) Device comprising a first file server having associated therewith a proprietary operating and file management system, the Network-Attached Storage (NAS) Device in communication with the media management component, and a data source connected to the management server, the method comprising: receiving a request to store source data on the Network-Attached Storage (NAS) Device, wherein the source data comprises multiple data files;combining with a media management component, a plurality of the multiple data files in the source data into at least one chunk of data;adding with the media management component, at least a first header to the chunk of data, wherein the first header is compliant with the Network Data Management Protocol;sending with the media agent a first data structure to a second file server that is remotely located from the Network-Attached Storage (NAS) Device based on the Network Data Management Protocol, the first data structure comprising at least the first header and the chunk of data;creating a second data structure with the file server by adding with the second file server, at least a second header to the first file structure, the second header comprising at least a first set of file markers that identify the plurality of data files in the chunk of data, the second file server further adding a trailer to the first data structure, the trailer comprising at least a second set of file markers that identify the plurality of data files in the chunk of data; andwriting the second data structure to the Network-Attached Storage (NAS) Device;retrieving with the second file server the second data structure from the NAS device;separating with the second file server, the second header and trailer from the first header and the chunk of data, and using the separated second header and trailer to create chunk metadata that identifies the plurality of data files in the chunk;providing with the second file server, the first header, the chunk of data and the chunk metadata to the media agent component; andunpacking with the media agent, the plurality of files in the chunk of data based on the chunk metadata. 2. The method of claim 1, wherein the writing the data payload is performed by the second file server. 3. The method of claim 1, wherein respective chunk metadata is added for each chunk of data. 4. A system for protecting data, the system comprising: a management server;a data source connected to the management server, the data source including source data, wherein the source data comprises multiple data files;a media management component connected to the management server, the media agent configured to: combine with a media management component, a plurality of the multiple data files in the source data into at least one chunk of data;add at least a first header to the chunk of data, wherein the first header is compliant with the Network Data Management Protocol;send the first header and the chunk of data over a network based on the Network Data Management Protocol;create chunk metadata about the multiple data files in the chunk of data; andat least one Network-Attached Storage (NAS) Device comprising a first file server having associated therewith an operating and file management system, the Network-Attached Storage (NAS) Device in communication with the media management component,a second file server that is remotely located from the Network-Attached Storage (NAS) Device, wherein the second file server is configured to: receive the first header and the chunk of data over the network based on the Network Data Management Protocol;receive the chunk metadata about the multiple data files in the chunk of data;to add at least a second header to the chunk of data, the second header comprising a first portion of the chunk metadata, wherein the second header comprises at least as first set of file markers that identify the plurality of data files in the chunk of data,to add a trailer to the chunk of data, the trailer comprising a second portion of the chunk metadata, wherein the trailer comprises at least a second set of file markers that identify the plurality of data files in the chunk of data;to write a data payload comprising the metadata and the chunk to the Network-Attached Storage (NAS) Device;retrieve the data payload from the NAS device;separate from the data payload the second header and trailer from the first header and the chunk of data;use the separated second header and trailer to recreate chunk metadata; andprovide the first header, the chunk of data and the recreated chunk metadata to the media agent component; andwherein with the media agent is further configured to unpack the plurality of files in the chunk of data based on the recreated chunk metadata. 5. The system of claim 4, wherein the media management component directs the file server to write the source data and metadata to the Network-Attached Storage (NAS) Device. 6. The system of claim 4, wherein the media management component generates the metadata. 7. The system of claim 4, wherein metadata is added for each chunk of source data.
