SharePoint 2010 Farm configuration backup and Clean up Script

I have to take the backup of the farm while excluding the Web Applicaitons and schedule it each night. Also, part of backup strategy do includes cleaning the old backups.

Have written the script to backup the farm configurations (Intimate farm admin with Email for success and failure) and clean old backup folder. Scripts could be downloaded from below mentioned location

These Powershell could be scheduled through task scheduler for creating farm configuration backup and delete the old one based on Retention period.
