That is fine if a user can insert the media from one drive to the
other. If they are in separate locations or you do not want to switch
media back and forth between devices its best to make them different
media type so bacula does not request media that you will not have.

I am confused at that. A single volume can only have 1 label.

Also you really should be limiting your volume size on both media in
some way (max volume size, use volume once ...) otherwise you will
have to recycle the entire volume when it eventually fills up.

I think when you created what you call a new label you actually
created a second volume on the hard drive.
