and Aging<a class="headerlink" href="#controlling-file-versions-and-aging" title="Permalink to this headline">¶</a></h1> <p>The Versions app (files_versions) expires old file versions automatically to ensure that users don’t exceed their storage quotas. This is the default pattern used to delete old versions:</p> <ul class="simple"> <li>For the first second we keep one version</li> <li>For the first 10 seconds Nextcloud keeps one version every 2 seconds</li> <li>For the first minute Nextcloud keeps one version every 10 seconds</li> <li>For the first hour Nextcloud keeps one version every minute</li> <li>For the first 24 hours Nextcloud keeps one version every hour</li> <li>For the first 30 days Nextcloud keeps one version every day</li> <li>After the first 30 days Nextcloud keeps one version every week</li> </ul> <p>The versions are adjusted along this pattern every time a new version is created.</p> <p>The Versions app never uses more that 50% of the user’s currently available free space. If the stored versions exceed this limit, Nextcloud deletes the oldest file versions until it meets the disk space limit again.</p> <p>You may alter the default pattern in <code class="docutils literal"><span class="pre">config.php</span></code>. The default setting is <code class="docutils literal"><span class="pre">auto</span></code>, which sets the default pattern:</p> <div class="highlight-python"><div class="highlight"><pre>'versions_retention_obligation' => 'auto', </pre></div> </div> <p>Additional options are:</p> <ul> <li><dl class="first docutils"> <dt><code class="docutils literal"><span class="pre">D,</span> <span class="pre">auto</span></code></dt> <dd><p class="first last">Keep versions at least for D days, apply expiration rules to all versions that are older than D days</p> </dd> </dl> </li> <li><dl class="first docutils"> <dt><code class="docutils literal"><span class="pre">auto,</span> <span class="pre">D</span></code></dt> <dd><p class="first last">Delete all versions that are older than D days automatically, delete other versions according to expiration rules</p> </dd> </dl> </li> <li><dl class="first docutils"> <dt><code class="docutils literal"><span class="pre">D1,</span> <span class="pre">D2</span></code></dt> <dd><p class="first last">Keep versions for at least D1 days and delete when they exceed D2 days.</p> </dd> </dl> </li> <li><dl class="first docutils"> <dt><code class="docutils literal"><span class="pre">disabled</span></code></dt> <dd><p class="first last">Disable Versions; no files will be deleted.</p> </dd> </dl> </li> </ul> </div> <ul class="prevnext-title list-unstyled list-inline"> <li class="prev"> <a href="previews_configuration.html" title="Previous Chapter: Previews Configuration"><span class="glyphicon glyphicon-chevron-left visible-sm"></span><span class="hidden-sm">« Previews Conf...</span> </a> </li> <li class="next"> <a href="../file_workflows/index.html" title="Next Chapter: File Workflows"><span class="glyphicon glyphicon-chevron-right visible-sm"></span><span class="hidden-sm">File Workflows »</span> </a> </li> </ul> </div> </div> </div> </main> </div> </div> </body> </html>
