SQL Server backup fails from vb6 application

I have a backup stored procedure gratiously provided by a member of this great establishment.  It runs fine from the server but fails occasionally when run from my vb6 app.  It doesn't timeout because it only runs about 20 seconds and the timeout is set for 60 seconds.

The error message simply says: 'Backup Failed'

Any ideas would be appreciated!!!

Does the VB6 application run with the same login credentials as when you run it from the server?  What does the proc do?

Thanks for the response!!!

Attached is the stored procedure that I run from vb6.  The error I get is:Backup Failed
The application logs into the SQLServer database and calls the attached.

Thanks,
