Hi MichaelT,

Thank you for the log, we have checked it and found out that you get the following error message:

Failed to execute “sp_addumpdevice” SQL procedure because of the permission error. Need to be a member of diskadmin server role and have permission to write to disk. User: —> System.Data.SqlClient.SqlException: User does not have permission to perform this action.

That error message happens when the application tries to remove a backup after the compression and means that a databases’ user doesn’t have permissions to delete that temporary file. Could you please check this?

Sorry for the inconvenience.

I found out that my Database user is not a diskadmin SQL server role. After I checked diskadmin from SQL management studio. It works great now.

Thanks
