I thought I had up to date backups with my TM...no errors in logs and showing hourly backups completed.
However, I found out the hard way this is not true all the time.
I had to reload my Mini at the recommendation of AppleCare because a failed removal of a Bootcamp partition was locking up the Mini upon restart.
Well, SL was reloaded and I told it to restore data from my TM backup.
Low and behold, the last date of "up to date" media was dated 3/5/10! So I lost over a week's mail, iCal appts, taxes!, financials, iTunes, etc.
