The laptop (TP600E) is coupled to the server through a wireless connected Linksys router WRT54G. The laptop adapter is WPC54G and is placed 1½ m from the router. The router connects to the internet with a broadband connection (5Mbit/s) and to the server through a wired connection. > > Also, some people have had success with Heartbeat Interval for FD and SD > in similar situations (this specific error is pretty unique according to > google, though).

I have just started a fresh back-up of the laptop and it seems to get going now without problems. -- Erik P.
