Backup Files and Folders to Network Storage

I need to backup files and folders from my server to a network storage.

Currently running Windows Server 2012 Standard R2.

My network storage was WD My Cloud 2TB.

I don't wish to use the Windows Server Backup feature because it convert the backup files into image file. I need it just to create a new  folder every time it backup/copy my files from the server to the network storage. Without overwrite it the old files.
