In case the computer on which the management server is installed gets corrupted, you should back up the private key and the certificate.
The JKS Keystore file is backed up during the initial installation. A file that is called
server_timestamp.xml is also backed up. The JKS Keystore file includes the server's private and public key pair and the self-signed certificate.
To back up a server certificate
In the console, click Admin, and then click Servers.
Under Servers, click the management server whose server certificate you want to back up.
Under Tasks, click Manage Server Certificate, and then click Next.
In the Manage Server Certificate panel, click Back up the server certificate and then click Next.
In the Back Up Server Certificate panel, click Browse to specify a backup folder, and then click Open.
Note that you back up the management server certificate into the same folder.
In the Backup Server Certificate panel, click Next.
