Hi guys, I just imported 20GB of HD video from my iPhone 4. But before I delete it, I want to make sure it's backed up, but it seems my Time Machine backup won't take note of the changes to my HDD. It just backs up a few KB and acts like my backup is up to date, when in reality it isn't. I've done a eject, restart, and verify disk to no avail. I'll be pissed if I have to start my backup fresh again as it isn't the first time. Thanks in advance.
