Hi Everyone - I got a new AIR and I used migration assistant from my old MBP on SL. I was prompted to inherit the backup history in Time Machine and I choose to do so. My Air has been backing up just fine through USB since then. Today I went into time machine and I noticed the time line on the right hand side. None of the dates preceding my Air are highlighted and thus I can not go back to those old files. Has anyone seen this? Am I doing something wrong?
