<p>I’ve been using Samba with the <code>time machine</code> setting for years to back up the couple of Macs I own. I’ve recently been running into issues with Time Machine backups erroring out with <code>"The network backup disk does not support the required capabilities"</code>. Poking around the Internet didn’t really point at an obvious culprit until I found some mumblings about this potentially begin a disk space issue.</p>
