I'm running Mountain Lion on a late 2012 MacBook Pro with Retina.

I have an external drive I use for extra storage, as well as one I use for Time Machine backups of both my MacBook HD and the storage drive.

Recently I had to reformat the storage drive and restore from the Time Machine backup. I was surprised to find that some changes I'd made had never been backed up. The two I noticed were:

  • In August I converted a couple thousand video files, over a few dozen folders, from AVI to MP4. While the Time Machine backup reflected this for some folders, in other folders I found the original AVI files instead. (My last backup was a few weeks after I converted them.)
  • In one folder I'd renamed all of the files (a few dozen video files), a few months ago. In Time Machine, they had the original file names. (These were not videos I ever converted.)

This has got me worried that Time Machine isn't doing the most complete backup. So I have two questions:

  1. Is this expected behavior for Time Machine, and
  2. If so, how do I go about forcing certain changes (like these) to be backed up?
 
TM doesn't work optimally if you leave it a long time between backups.

That having been said, are you viewing TM's backup in the TM app, or the Finder?

There are utilities for seeing what TM backed up in a particular snapshot, but I don't think you can force TM to backup a certain file --- except by modifying the file.
