    I decided to reinstall Leopard, Erase and Install. Everything runs much faster of course. I'm doing some restoring from my Time Machine HD. I don't want a complete restore, I'm just grabbing folders here and there from my TM HD and restoring it. I'm doing a backup now and so far it has deleted over 20GB of my backups and it doesn't seem to be stopping. Is there a reason for this?

    Any update on this one? I've wanted to do the same thing. Maybe not after reading this though.

    Time Machine works by incrementally backing up the changes made on your disk. When the TM disk runs out of space it will start deleting the oldest backups to make way for the new backups. Ordinarily new backups will be small since the disk will be changing little. If you erase and install then basically you've changed every file on the disk and Time Machine will want to backup all those files. This will take up a lot of space which it will make by deleting lots of old backups.
