# Restoring a Configuration File

Restoring configurations consist of restoring configurations on the ATIC Management center and those on the anti-DDoS device.

#### Context

ATIC management center can only be restored by the configuration file with the same version.

Ensure that other administrators are offline during the database restore. Otherwise, operating the database by them may interrupt the restore.

Choose System > System Administrators > Online Administrator to check whether other administrators are online.

#### Procedure

1. Choose System > Data Maintenance > System Backup.
2. Click and the ATIC services will restart after data recovery. Then click OK to start restoring the configuration file.
3. When the configuration file is restored, click OK to close the dialog box.
4. Re-log in to the ATIC Management center.
