Hi
There is multiple factors you need do fallow before restoring.
The DNA Center restore process restores the database and files. The restore process does not restore your network state and any changes made since the last backup, including any new network policies that have been created, any new or updated passwords, or any new or updated certificates and trustpool bundles. Note During a restore, the backup file overwrites the current database. While a restore is in progress, you are not be able to open or access any windows in DNA Center. If the restore process is successful, you are logged out of DNA Center. You will need to log back in. If the restore process is unsuccessful, you receive an unsuccessful restore notification. Because the database might be in an inconsistent state, we recommend that you do not use the database and contact technical support for additional actions to take.
(Optional) Check whether the restore process was successful. To review the backup and restore history in the Backup & Restore window, proceed to Step 4. To review the backup and restore history in Grapevine, follow these steps: a) Using a Secure Shell (SSH) client, log into the appliance using the IP address that you specified during the initial configuration. The IP address to enter for the SSH client is the IP address that you configured for the network adapter. This IP address connects the appliance to the external network. Note b) When prompted, enter grapevine as your Linux username and the password for SSH access. c) Enter the grape backup display command at the prompt. Check that the command output shows the restore process was completed and successful. Look for the property operation marked restore in the command output, with the latest start time followed by a success status. d) Using the Secure Shell (SSH) client, log out of the appliance
