Whilst adding a new remote server to our BackupPC configuration, it threw the following error

Contents of file /Volumes/2TB/backuppc/pc/www.server.co.uk/LOG.102011, modified 2011-10-25 13:10:23

2011-10-25 12:00:00 ping too slow: 22.21msec
2011-10-25 13:00:01 ping too slow: 49.63msec
2011-10-25 13:10:23 ping too slow: 47.79msec

and refusing to back up the server! After browsing the documentation I discovered the following configuration option

$Conf{PingMaxMsec} = 20;

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.

After altering the host’s config file and adding that parameter with a value of 200 the server then started to back up!
