as an example if you want to be able to wake on lan :
config setprop backuppc sudo `config getprop backuppc sudo`,/sbin/ether-wake
signal-event backuppc-update
then simply add a script to your prebackup command or your ping command like :
#!/bin/sh
# Set the mac address for each host
host1_mac=<mac address>
host1_name=<host name>
host2_mac=<mac address>
host2_name=<host name>
# How long does the host take to boot
boottime=120
# Which interface to send the WoL packets out of
interface=eth0
# Function to check if the host pings
pingcheck()
{
ping -w 5 -c 2 $1
export pingstatus=$?
}
case $1 in
host1)
sudo etherwake -i $interface $host1_mac
sleep $boottime
pingcheck $host1_name
exit $pingstatus
;;
host2)
sudo etherwake -i $interface $host2_mac
sleep $boottime
pingcheck $host2_name
exit $pingstatus

echo "Unknown machine $1"
