I have written a bash script that performs a remote wakeup of my backup
server using etherwake. The script is initiated from my backup client -
not the server.
ping -c 3 $server > /dev/null
if [ $? -eq 0 ]
then
echo "$server is already up and running\n"
else
#Wake up server
echo "Waking up server $server\n"
sudo /usr/sbin/etherwake -D -i eth0 00:0c:6e:xx:xx:xx
sleep 120
fi
Next, it runs rsync to perform the backup. Substitute your own backup
command as you see fit.
rsync -aRzv --progress --delete --log-file=/tmp/rsync.log \
`cat /home/user/rsynclist.txt` $server:/backup/user
After the backup is completed, it creates an AT job to poweroff the backup
server 5 minutes later.
future=$(date -d "5 minutes" | awk '{ print $4 }'| cut -d ':' -f1,2)
ssh [EMAIL PROTECTED] <[EMAIL PROTECTED]> "echo 'sudo /sbin/ethtool -s eth0
wol g;
sudo \
/sbin/poweroff' | at $future"
The "ethtool -s eth0 wol g" command puts the backup server's NIC in the
proper sleep mode for subsequent remote wake calls.
