As of Feb 4, 2012, I am running all of Apple's updates to OS X 10.7.3  My Time Machine backups are written to an external 1TB Toshiba drive that has well over 900MB of free space.  I've noticed, however, that my backups fail with an "Unable to complete ..." message whenever iTunes is running.  Thsu far I haven't been had time to determine whether the problem is iTunes pure and simple or whether it is related to:  (a) iTunes transmitting (wired) to my Airport Express; or (b) importing CD content into iTunes.  Otherwise, Time Machine backups work without issue.
