Ok Id like to use one of the HD inside the Synology NAS to back up the second and my notebook hard drive.
Is this possible?
I think what your are asking is
laptop -> Synology disk1
Synology disk1 -> Synology disk2
That should not be an issue. You would use normal backup software on your laptop to backup to the network drive (Synology disk1). Then you would let the Synology back itself up.
I recommend Acronis for backup software but there are other choices. Acronis allows you to do a full disk image as well as file by file backups for selected items.
