I'm completely new to Amanda and need a little coaching. I've read through quite a bit of documentation but the picture still isn't clear.
I have a NAS device thats capable of supporting several protocols including SFTP and NFS (CIFS, AFS, etc). I'd prefer SFTP for security purposes but don't mind going NFS.
I have a number of Windows machines (2008r2) that need to be backed up. My backup server is Ubuntu 14.04.3. Windows agent on windows machine.
Can Amanda write to this NAS device via SFTP? If not, now about NFS? I assume I'd simply mount the NFS volume to my backup server and write to hard disk. Can the holding disk reside on the NAS device?

Can someone point me to an Amanda cookbook of sorts that describes the vtape (harddisk) configuration?
