title: Why is the compressed Subversion dump file larger than the original?
body: <p>We are using SVN 1.7 on Solaris 10. Recently we've introduced compressed, incremental backups.</p>
  
  <pre><code>$ svnadmin dump --quiet --incremental --revision 0:30700 /path/to/repo &gt; /path/to/dump
  $ gzip -1 /path/to/dump
  </code></pre>
  
  <p>The final gzipped dump file is larger (~850MB) than the original dump file (~500MB). I tried <code>gzip -9</code> as well but that still creates a larger file than the original (~650MB).</p>
