Creates dated folders for backing up files/folders on a schedule. Removes backups older than n days. Configuration via text file.

Introduction

This is a simple backup utility that creates dated backup folders. Dated Backup will remove backups older than N days.

Using the Code

This is the datedBackup.vbs file. The editor mangled some of the responses that are to be written to the HTML log files. If you choose to use any of this code, please download the zip so that you can see it in its original format. As you can see from line 1, you must specify the path to the dbsettings.config file. Once you have done that, you must edit the dbsettings.config file to backup the folders that you choose. Dbsettings is also where you enable/disable features of the script such as email notification. Currently this script will check our website for newer versions of itself and download if you choose. Have fun!

Should you decide to use this script or if you like the concept, let me know.
