I&#x27;ve had issues on (10.10 and 10.11) where FileVault 2 (FDE) irrevocably corrupts some metadata and it cannot be fixed by Disk Utility.  (It &quot;works&quot;, but performance is terrible and free space is wrong.)  Reinstalling by rsyncing latest backup to recreating volumes fixes it.<p>Also, the usual popular, secure rsync-like service: tarsnap ( <a href="https:&#x2F;&#x2F;www.tarsnap.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.tarsnap.com&#x2F;</a> )<p><pre><code>    brew install tarsnap
</code></pre>
