 ```

 For example:
 
 ```text
 # systemctl stop eportal
-# cp -f /path/to/backup_dir/* /usr/share/kcare-eportal/
-# chown nginx:nginx /usr/share/kcare-eportal/*.sqlite*
-# systemctl start eportal
-```
-
-Also, you need to check remote patchsource settings (Login, Password, Download URL in eportal UI), and after it download patches
-
-```text
+# kc.eportal restore /var/lib/eportal/backups/eportal_backup.tar.gz
 # kc.eportal kcare download-missing
 # kc.eportal libcare download-missing
 # kc.eportal qemu download-missing
-# kc.eportal db download-missing

+`download-missing` commands ensure patchset state on disk corresponds with a state
+in db.
