+openclaw gateway stop
+
+# 2. Backup current (safety)
+mv ~/.openclaw ~/.openclaw-old
+
+# 3. Extract backup
+cd ~
+tar -xzf ~/openclaw-backups/openclaw-YYYY-MM-DD_HHMM.tar.gz
+
+# 4. Start OpenClaw
+openclaw gateway start
+
+# 5. Verify
+openclaw status
+```
+
+## Rollback if Restore Fails
+
+```bash
+rm -rf ~/.openclaw
+mv ~/.openclaw-old ~/.openclaw
+openclaw gateway start
+```
