It is not necessary to have a ping response under 20msec and when you 
connect to your backuppc-server via a tunnel through the internet you 
will not get this response times :-)

In order to change the time after a ping is called "to slow" you can 
edit the /etc/backuppc/config.pl

$Conf{PingMaxMsec} = 200;

Maximum round-trip ping time in milliseconds. This threshold is set to 
avoid backing up PCs that are remotely connected through WAN or dialup 
connections. The output from ping -s (assuming it is supported on your 
system) is used to check the round-trip packet time. On your local LAN 
round-trip times should be much less than 20msec. On most WAN or dialup 
connections the round-trip time will be typically more than 20msec. Tune 
if necessary.
