Open Directory and Server Admin Backup

I couldn't find any obvious easy way to have sceduled rolling backups for Open Directory and Server Admin under OS X Server 10.5 so these two scripts which are essentialy one do the job together. I had these running on the first of the month creating an archive of Open Directory and plists of Server Admin settings.  

I cron jobbed the saBackup script and have the odBackup script in the same folder so the saBackup script can call it;

saBackup.sh:

#!/bin/bash

# This backup script will backup all Server Admin services
# (even those not in use to save tracking what is and is not being used)
# and make the sparse image of the OD Master generated by slapconfig -backupdb

echo "Starting at `date +%H:%M:%S`"

# Set the backup path to be in a sub folder
backupPath="/some_drive/Backups/OpenDirectory/`date +%Y-%m-%d`/"
echo "Backing up ServerAdmin to: $backupPath"

# Check the backup path exists and set permissions, 
# If the folder doesnt exist it will be created
mkdir -p $backupPath
chmod 750 $backupPath

# Export each server admin service into the backup directory
services=`serveradmin list`
for service in $services; do
	echo "Backing up: $service"
	result=`serveradmin -x settings $service > $backupPath/$service.plist`
	if [ $? -ne 0 ]; then
		echo " ...failed!"
		echo "$result\n"
	fi
	sleep 1
done

# call the OD backup script (because of the use of 'expect' as its shell it is its own script)
./odBackup

echo "Finished at `date +%H:%M:%S`"

Note: the date is being passed as the password for the OD archive, it must have a password, so its worth changing this! Also, these scripts must be called by root to use 'slapconfig -backupdb'

odBackup.sh:
#!/usr/bin/expect -f

# We can't parse variables from the SA backup script so the same variables must be redefined here
set date [timestamp -format "%Y-%m-%d"]
set path "/some_drive/Backups/OpenDirectory/"

# Create the OD Master sprase image archive
spawn /usr/sbin/slapconfig -backupdb $path$date/odBackup
expect "Enter archive password"
send "$date\r"
expect eof
