I normally store my Linux system backup files to CD's. I want to move the backup files to a 2012 Windows Server I use for management purposes. I am limited to Linux CLI and 2012 Server services, no 3rd party software allowed.
Your options boil down to 3 basic methods:
Sneakernet: That is, copy your files from the Linux server to a removable medium such as a flash drive or an external hard drive. It sounds like you already have the files on physical CD. If the Windows server has an optical drive, just pop the CD's into the drive and copy the files.
Mount a Windows share on the Linux server: For that you'll probably need to install some packages on the Linux server. The specific packages depend on your distro.
Mount an NFS share on your Windows server. You'll need to install the NFS Client, which is part of Windows Features.
Option 1 involves copying the files twice, but is probably easier overall.
