OpenVPN can drop the tunnel connection due to inactivity without
dropping the TUN interface on either side of the tunnel. You must use
OpenVPN's '--persist-tun' flag to prevent a ping-restart from closing
and reopening the TUN interface or re-running the up and down scripts.
If the TUN interface is restarted it will break Bacula's persistent TCP
connections. Both ends of the tunnel must have the 'persist-tun' flag
set. Also, if Bacula backups are using compression, then OpenVPN's LZO
compression should be turned off.
