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?

If you have two full back up files, then yes you can delete the old one, but be careful that you don't need anything. This happened to me when my PowerBook came back from repair. Time Machine would not recognize the original backups, so created a new set of backups. I saw them as "PowerBook Backup" and "PowerBook Backup_1." Is that what you see? 2 different folders? You can also manually open the old backup and delete selected backups for certain dates. I eventually used this option and deleted all except for the oldest and most recent backups in that folder. I even did a system restore from those backups, and I've been able to restore individual files from those backups.
I'd love to figure out how to use Time Machine to create backups on 2 external drives. Then I could alternate every other day and keep one drive somewhere else. But if I try this, Time Machine gets confused, and it thinks that I am doing a new backup each time. It will not find the previous backups to add to after it creates a backup on another drive. Maybe they will fix this in Snow Leopard.
