# Restore from the secondary backup
-If unfortunately the hard drive on your primary device is dead, you can bring up the secondary setup as primary one. The photo and video assets are already backup on the secondary hard drive, as well as the database. You can copy the "assets.db" in the user directory on hard drive to "/opt/lomorage/var/assets.db", and change the "home_dir" in table "user" for each user in "assets.db". We promise will let this process less painful, but for now, you have to do that manually, if you have the problem and can't figure it by yourself, join our [slack channel](https://join.slack.com/t/lomorage/shared_invite/enQtODc4MTE5ODQzNzkyLTRlY2U4MTQ1YjczYjBhMDcwMmExYTUxNTg2NTE5YmRkZjg2ZWQwZjg1MjEwMjQzZWVjMmEwZjk3ZGIyODY4ODM) or reach us via [email](mailto: support@lomorage.com), and we will help you solve it.

# 从备份恢复
