I went about 3 weeks without connecting my MBP to my Time Machine drive. Last night when I did it it wasn't seeming to update so I clicked on the "Backup Now" button and went to bed. I woke up this morning to find that Time Machine had created a second full backup of my MBP on the external hard drive. That's fine but what I'm wandering is whether I can blow away the original now (as the external HD is almost full). Seems like I can but I want to be careful.
Also, any idea why this happened? How do you kick off only an incremental backup rather than a brand new full backup?
