It is good practice to take backup media off site in case of a disaster. In the shell script example the backup media is another server providing an NFS share. In all likelyhood taking the NFS server to another location would not be practical. Depending upon connection speeds it may be an option to copy the archive file over a WAN link to a server in another location.
