Full backup on Windows Server 2008 R2

Hi All,

I have a problem similar to the following one:

http://social.technet.microsoft.com/Forums/en/windowsbackup/thread/ff4cbf80-0146-4682-bcf2-92fc0d093284

The question is:

We ordered our latest DELL PowerEdge server without OS and after installing Windows Server 2008 R2 x64 discovered this hidden 2GB OS partition. After assigning a drive letter Z: to it I discovered that it's empty (I don't see any file or folder in it) but the hard disk drive / properties reports 14.4MB of used space and 1.98GB of free space. Even showing hidden files and folder I cannot understand what those 14.4MB refer to.

Is this partition useful or not, shall I delete it or convert it to NTFS? We need to start doing the full backup on this server.

Thanks,

Alberto
