what does time machine backup include?
How to include USB storage in the time machine backup.
Since I have plenty of datas on my Wd 1TB drive. I wonder if I can backup on time machine or if TM does it only with the very Mac itself only.?
Can you provide a exact procedure to include USB disk, please?
