I updated my MBP and recently ran Onyx for some maintenance and had to repair the HD via Disc Utilities (I think it was a HD repair...can't remember exactly).

My TM was not working properly but finely got it to complete a backup. However, Spotlight is not working. It states 3 months for re-indexing then it was down to 3 days but now it's back up to 3 months and the progress bar has reset itself. At the same time, it seems like there are excessively large TM backups now. Most recent was 64 GB but I haven't done any work other than surf the web.

Any suggestions what I can do to help Spotlight along?
