This freaked me out because backups disappeared all of a sudden.</p> <p>I was looking for backups with:</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span style="white-space:pre;-webkit-user-select:none;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f">1</span><span>docker compose exec backup borgmatic list </span></span></code></pre></div><p>And there was nothing.</p> <p>The cause of the problem was the <a href="https://torsion.org/borgmatic/reference/configuration/archive-name-format/#:~:text=This%20example%20means,a%20particular%20format.">default backup naming convention</a> used by borgmatic, which uses the hostname, and which changes on each container restart.</p>
