Name: GPOBackup.ps1
This script will check for GPO's modified in the last day and then only export the data if changes have been made. This will keep the number of backups and files down to the minimun needed.
This script will create GPO Reports to track changes and backup the GPO's so you can easily locate changes that have been made and recover. Below is a list of the files created from this script: -----.zip - This contains a backup of all your GPO's the folder is create with the name for each GPO for easy Recovery or viewing ------GPOChanges.csv - This file contains the Changed GPO Information like Name, ID, Owner, Domain, Creation Time, & Modified Time. ------GPOList.csv - This file contains GPO Information like Name, ID, Owner, Domain, Creation Time, & Modified Time. ------GPOReport.csv - This file Contains GPO Information like Name, Links, Revision Number, & Security Filtering ------GPOReport.xml - This a backup of all the GPO's in a single file incase you need to look for a setting and do not know which GPO it is on. ------GPOReport.html - This a backup of all the GPO's in a single file incase you need to look for a setting and do not know which GPO it is on. ------UnlinkedGPOReport.csv - This file Contains GPO Information like Name, ID, Status, Creation Time, & Modified Time ------WMIFiltersExport.csv - This file Contains WMI Filters Information configured in GPMC
This script was based off of one from Microsoft to backup GPO's by name, I have added more as the need and to make things simplier when backup up GPO's
