Scheduling SharePoint Backup : Part 2

A while ago I posted a SharePoint Backup script so that it is possible to schedule a SharePoint Backup. I had to make some adjustments to the script because it contains small errors. The adjustments I had to make were:

• When you perform multiple differential backups in a week you will receive multiple e-mails for one backup.
• I have created more properties so that you can alter the script from the top.
• You do not have to delete a method when you choose the differential backup method
• I cleaned the script up a little bit.

 ''This is a VBScript for scheduling the SharePoint backup.
 ''The script has the ability to be scheduled as an differential
 ''backup or a full backup. This script will also send an email
 ''when the job is finished.
