    As an update, I have "fixed" the problem, although I have no idea why the change I made would have fixed it.  The user library that I wanted to have backed up was pinned to my finder sidebar.  It was not being backed up, even though it had not been excluded.  I removed it from the sidebar, and on the next Time Machine backup, it was included.  Makes no sense, but that honestly seems to be what happened.

    You wrote before that the files were now being backed up. Has that changed? How do you know they're not being backed up?

    Oh god the exact same thing has just happened to me. I got a replacement hard drive, swapped out my old one, only to find that my time machine backup was incomplete

     

    At first I thought I had accidentally excluded System Files, so I swapped back in my old hard drive and checked. Nothing was excluded (supposedly). Anyways I found a CNET article telling me to turn SkipSystemFiles to false through terminal so I did that, re-did a WHOLE NEW backup on a new hard drive and system files are still absent!!

    So finally at the end of the day I come here and see your comment. Same issue. All my system files in "ExcludeByPath" just randomly. For what its worth, I too have Silverlight installed.

    Have you reported the potential bug in the API?

    I am on Mountain Lion moved from Snow Leopard.

     

    Moving the Applications folder out of the finder sidebar also fixed my problem.

    I did a re-boot after removing the folder. A window came up asking me if I want to use the current drive I was using for time machine backups. I agreed and a backup started.

    All my missing folders are now backing up.

    One of those mysterious Lion things going on.

    The strange thing is that a MacbookPro Retina has the folders in the Finder sidebar and there is no problem with Time Machine.

    TM is not backing up my Applications, Library and System files either.

     

    I have not excluded anything from my TM backups.

     

    I tried the Terminal code, but it could not find:

    domain (/Library,Prefersnces/com.apple.TimeMachine.plist) not found

     

    Presumably because I have not excluded anything.

     

    Any ideas hoew I can make TM back up these files.

     

    Thanks.

    In view of all the problems being reported here, why not just dump Time Machine and use a reliable cloning utility such as SuperDuper or Carbon Copy Cloner? Trying to get Time Machine to behave properly sounds like flogging a dead horse. If TM isn't reliable, what use is it?

    The plist will always be there, as long as Time Machine has been turned on. Instead of doing it via Terminal, try turning off Time Machine, finding the file via Finder (Go>Go to folder> "/Library/Preferences") and deleting the TimeMachine plist, and then turning Time Machine back on. That should create a brand new plist with nothing excluded. At least, this worked for me.

    The TM plist was there.

     

    Followed your instructions.

     

    TM still does not backup my Applications, Library nor System files.

    Well what does the plist say now? Are the files still there in <ExcludeByPath> ?

    Ok well then are you sure it got deleted in the first place? Make sure you turn off Time Machine and quit System Preferences and everything, then delete, then Empty Trash, make sure its gone, and then turn on Time Machine again. If <ExcludeByPath> is still there, you might want to try editing the plist in TextEdit or something and removing then manually but that is a bit dangerous.
