You could reprocess the dumper output before storing it by replacing any sequence of one (or two) or more spaces by a single space: 
$dumper_output =~ s/ +/ /g;

The result will not be pretty, but you'll save quite a bit of space.

Or you could use a module more dedicated to what you want to do than Data::Dumper, such as, for example Storable, which produces a more compact output.

Update: crossed out my first suggestion because, as pointed out by Anonymous Monk below, it might mess things up is either keys or values of the hash have multiple spaces.

Je suis Charlie.
