+<p>Hardware failure abroad is a predictable event. Treat backups as part of your product delivery system.</p>
+
+<h2>Minimum viable redundancy</h2>
+<ul>
+  <li>Cloud sync for active project files</li>
+  <li>Encrypted offline backup of critical documents</li>
+  <li>Password manager with offline access</li>
+  <li>A written restore checklist you have tested once</li>
+</ul>
+
+<h2>Laptop risk controls</h2>
+<p>Keep a thin secondary device if your income is device-critical—even a tablet that can handle docs and calls can bridge a week. Know where you can buy chargers locally.</p>
+
+<h2>Test restores, not only backups</h2>
+<p>Backups that have never been restored are stories. Once a quarter, restore a sample folder on a clean machine or profile and time how long recovery takes.</p>
+
+<h2>Incident communication</h2>
+<p>Have a template message for clients: what happened, what still works, when you will next update. Calm process protects reputation while you rebuild the stack.</p>
