Hi, please note WWWBackup doesn't need to run if you are not using your computer. If this is a desktop PC and if you are logged off, then WWWBackup doesn't need to run.
If you are using it on a server, the current version WWWBackup works just fine; however, it cannot run as a service. We will implement this feature in a future version. For now, you can also use Windows Task Scheduler to run it as a service.
To select multiple backup source folders, please hold Shfit or Ctrl key, and select multiple folders. You can also create multiple backup tasks to backup multiple folders.
