Thanks Michael
Those other options are what SSMS put there. I used the "wizard" and then did the "script to new window".
I did a test, but the size of the backup file was really small compared to the data file, that is why I was asking.
If I wanted to backup only one or two of the filegroups, would it be better to use the "File" Option, or the "FileGroup" option? That is where I am confused also.
Thanks for your assistance with this.
