# Sync the media from our shared NFS directory to our local backup copy.

# Two issues this solves: 
#       - Only sync if the NFS mount is operational (so as to not wipe out the backups)
#       - Ensure that the local copy is read-only for apache so that file-uploads won't
#         succeed in read-only mode.
