Hey so I've never seen this before... Typically the only time my spotlight needs to reindex is when the computer hits some error and turns off right away. But this is odd... it want to reindex my time machine backups, and it says it's going to take like 40 hours to do... this just happened today after being away for a 3 day business trip... any ideas what this might be? Anyone seen this? I'm on the most recent i7 MBP w/ 512gb SSD on the most recent Time Capsule 1TB.
