Since I have upgraded to Lion I have noticed my Time Machine Backup is taking forever... like it's stuck on 'Preparing Backup'. Console in the system.log says that a Deep Scan is required due to subdirectories... I've let it run now for over half an hour and it's still on Preparing Backup. This is the third time I have tried to do it. The other two times I had to shut my MBP because I had to leave (and take the laptop with me). Does it usually take this long to prepare a backup when it needs to deep scan? (I don't have a HUGE amount of stuff on my HD...It's a 320 GB with roughly 250 GB free. How long should I let it run for? The laptop is getting a tad warm in the process.
