My current iTunes rsync backup script

The other day I was looking for a backup solution for two laptops. While I was unable to get the exact results I was looking for I did create a nice bash script that detects the network, and if on my local network it will mount the share from my Airport Extreme and then rsync the data over.  I am sure there is plenty of room for improvement on this script, but it works quite well.

#!/bin/sh

ap=`/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | sed -e "s/^ *SSID: //p" -e d`

if [ $ap == "oxygen" ]
then
clear
echo "You are connected to Oxygen."
echo "Backup will now begin."
echo "Mounting network drive."
sudo mkdir /Volumes/music_backup
sudo /sbin/mount_afp afp://oxygen.local/Storage/ /Volumes/music_backup/
sudo /usr/bin/rsync --exclude .DS_Store --exclude .Trash --stats --progress --inplace --no-owner --no-group -vhlrutD --delete /Users/shelby/Music/iTunes/iTunes\ Media/Music/* /Volumes/music_backup/Music/shelby/
echo "Unmounting network drive."
sudo /sbin/umount /Volumes/music_backup
echo "Backup is complete."
else
clear
echo "You are not connected to Oxygen. Music will not be backed up at this time."
