I constantly get this warning in Matlab, which I run on the command line:

This process is attempting to exclude an item from Time Machine by path without administrator privileges. This is not supported.

What can I do to prevent this?

What part of your code is trying to alter Time Machine information? – Mark Oct 4 '11 at 16:21
no part at all... Matlab just starts spitting out this warning, even with me doing nothing – romeovs Oct 4 '11 at 16:50

Start Matlab as administrative user once so it can do the exclusion.

It is reported here, they claimed that the issue is for all version of Matlab on Mac OS X Lion. So I guess you could simply use sudo to get this problem done. And wait with more patient for a fix.

Running sudo matlab once worked for me. This assumes that /Applications/MATLAB_R20???.app/bin has been added to PATH.
