A method for managing data include obtaining, by a universal connector, a backup request for a set of files, in response to the backup request: performing a batching of file read requests for data associated with the set of files to obtain a set of file read batches, sending the set of file read batches to a network attached storage (NAS) server, obtaining a response for each of the set of file read batches from the NAS server, wherein the response for each of the set of file read batches comprise a portion of the data, wherein at least two responses for the set of file read batches are obtained in parallel, writing the portion of the data to a backup container in parallel with the obtaining, and initiating a backup of the set of files using the backup container after the writing is completed.
