Backup a host in BackupPC when PING was blocked on your network

When PING was blocked on your network, BackupPC can not backup hosts because it will stop the backup process when there is no ping response. Here is a workaround to make the backup happen:

Change the PingCMD (ping command) in the host setting of BackupPC webinterface:

1. Seclect the host then click "Edit Config" link.

2. In Backup Settings tab, PingCMD section, check "Override" and replace 

"$pingPath -c 1 $host" 
with
"/bin/echo"

3. Click "Save"
