Automatic backup of the key file
The automatic backup method is less secure, but it ensures that a backup copy of your key file exists.
This method requires that you create a non-encrypted policy to back up the key file. If the key file is lost, you can restore it from the non-encrypted backup.
The problem with this method is that a client's key file can be restored on a different client.
If you want to include the key file in the back up to a client, add the key file's path name to the client's include list.
Redirected restores require special configuration changes to allow a restore.
