Clone the Card Using balenaEtcher<\/h2>\n<p>Launch balenaEtcher and select the cloning function (<em>clone card<\/em>). Set your existing <a href=\"https:\/\/netguide.io\/smart-home\/category\/home-assistant\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"Home Assistant\">Home Assistant<\/a> card as the source and the new card as the target. Once started, balenaEtcher will handle both the cloning process and the subsequent verification.<\/p>\n\n<h2>4. Insert the New Card and Boot Up<\/h2>\n<p>Insert the newly written card into your hardware and reconnect the power supply. Once booted, the additional capacity of the larger card will be available right away.<\/p>\n\n<h2>Did It Work?<\/h2>\n<p>Your system should become accessible again as usual after booting. In the web interface, verify whether storage utilization has dropped and the total available storage matches the capacity of your new card. Backups can now be triggered again without warnings.<\/p>\n\n<h2>Troubleshooting<\/h2>\n<ul>\n  <li><strong>The interface reports connection errors or authentication issues:<\/strong> If data was corrupted during the cloning process, the system might be damaged. Repeat the cloning process, or flash a clean system image and restore a previously created backup.<\/li>\n  <li><strong>balenaEtcher throws an error:<\/strong> Ensure that the memory cards and card readers are properly connected to your computer and maintain a stable connection.<\/li>\n<\/ul>\n\n<p>With the cloned card in place, your home automation system is back up and running. If write loads continue to increase over time, migrating to an SSD might also be a worthwhile next step.<\/p>\n<p><em>Sources: <a href=\"https:\/\/community.home-assistant.io\/t\/cloning-sd-card-to-a-larger\/594390\" rel=\"nofollow noopener\" target=\"_blank\">Forum: Home Assistant Community<\/a>, <a href=\"https:\/\/www.home-assistant.io\/installation\/\" rel=\"nofollow noopener\" target=\"_blank\">home-assistant.io<\/a>, <a href=\"https:\/\/github.com\/home-assistant\/operating-system\" rel=\"nofollow noopener\" target=\"_blank\">github.com<\/a>, <a href=\"https:\/\/community.simon42.com\/t\/sd-karte-klonen-ha-nicht-mehr-erreichbar\/9697\" rel=\"nofollow noopener\" target=\"_blank\">community.simon42.com<\/a><\/em><\/p><div id=\"netgu-1201552346\" class=\"netgu-after-content netgu-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-6258556257245998\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-6258556257245998\" \ndata-ad-slot=\"4559785002\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>When storage space runs low in Home Assistant OS and backups start failing, switching to a larger SD card is the answer.
