Backing up external hard drive to 2nd external Time Machine hard drive
I have 1 Seagate external hard drive that is my designated Time Machine drive.
I have a 2nd Seagate external drive that is my primary location for all media - music, photos, video, etc.
The 2nd external hard drive is not backing up to Time Machine. It doesn't show up in the Time Machine options as a drive to exclude nor does the contents show up when I enter Time Machine.
1 - Is what I am trying to do possible?
2 - What steps do I need to take if the answer to #1 is 'YES'?
Thanks.
