I have almost completely rewritten the batchfile for it to meet my fancy ;)
Replaced blat with sendmail and using delage32 to cleanup previous backupfiles and logfiles.
Date and time variables are in European format, change this if you want/need to.
The first part declares a bunch of variables, read this carefully.

Hands down to Eric, he laid the foundation for me to create this.

Below the source I have created. Comments are welcome.
