Backing Up the Key File
It will be a time-consuming task to recover your system if you accidentally damage or delete the key file. Therefore, it is important to save a backup of your key file. It is recommended that every time you build a new key that you backup your latest key file to a safe location.
Note:
You only need to keep the latest version of your key file for your backup. The latest version contains a version history of previous keys.
