If it's Paclets that are at issue, then they go into a subdirectory of 
your $UserBaseDirectory, which for *nix is ~/.Mathematica (as you've seen).

You can readily change the value for $UserBaseDirectory so as, for 
example, to move it out from your user folder and hence avoid having it 
backed up with your other user data files. You do so by setting the 
desired value for the system environment variable MATHEMATICA_USERBASE.


or the corresponding page within the Mathematica Documentation Center.
