How do I see what files Time Machine is backing up to figure out what to exclude?

 

All of the sudden there is a dramatic increase in size and it won't back up.

 

Thanks

    It backs up everything unless you tell it not to.

    Thank you.

     

    Is there any way to see what changed recently that made it jump up or what the big files are so I can address it?

     

    Thanks

    Probably one cannot do better than this:

    Triple-click anywhere in the line below to select it:

     

    tmutil compare

     

    Copy the selected text to the Clipboard (command-C).

     

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Paste into the Terminal window (command-V).

     

    The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.

     

    Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.

     

    Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.

     

    Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.

     

    Files that you’ve excluded from backup, or that are excluded automatically, are ignored.

     

    At the end of the output, you’ll get some lines like the following:

     

    -------------------------------------

    Added:

    Removed:

    Changed:

     

    These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.
