Logging Jobs with Start-Transcript — Powershell (.ps1) scripts supports much better logging than SQL Server Agent or Windows Task Scheduler (WTS). The Start-Transcript command captures script and program output at the script level. This level of logging catches error messages that other logging strategies miss.
