    <ul class="small mb-2">
        <li>Each backup is a single <code>.zip</code> containing a full <strong>database SQL dump</strong> (patients, visits, fees, remaining payments, tests, ingredients, stock entries, usage, products, POS sales &amp; items, users/roles) plus all <strong>uploaded files</strong> (prescription slips, test images, product images) from <code>public/uploads</code>.</li>
        <li>Backups are stored in <code>storage/app/backups</code> — <strong>outside</strong> the public folder, so they are never directly reachable by URL. Downloads are served only through this admin-only page.</li>
        <li><strong>Automatic daily backup</strong> runs via the Laravel scheduler and old backups are pruned after {{ config('backup.keep_days') }} days.</li>
    </ul>
    <h6 class="border-bottom pb-2 mt-3">Scheduler / cron setup (VPS / cPanel)</h6>
    <p class="small mb-1">Add this single cron entry on the server so scheduled backups run:</p>
    <pre class="bg-light p-2 small mb-2">* * * * * php /path-to-project/artisan schedule:run &gt;&gt; /dev/null 2&gt;&amp;1</pre>
    <p class="small mb-0">Manual command anytime: <code>php artisan backup:run</code></p>
    <h6 class="border-bottom pb-2 mt-3">Restore (manual, for safety)</h6>
    <ol class="small mb-0">
        <li>Download the backup <code>.zip</code> and unzip it.</li>
        <li>Import <code>database.sql</code> into the database (phpMyAdmin / <code>mysql</code> CLI). <strong>This overwrites current data</strong> — do it on a staging copy first.</li>
        <li>Copy the <code>uploads/</code> folder from the zip back into the project's <code>public/uploads</code>.</li>
        <li>Restore should be performed by the developer/admin to avoid accidental data loss.</li>
    </ol>
