Solutions for backing up the KMS data files
The best solution for backing up KMS data files is to do so outside of the normal NetBackup process, or rely on pass phrase generated encryption keys to manually rebuild KMS. All of the keys can be generated by pass phrases. So if you have recorded all of the pass phrases, then you can recreate the KMS manually from the information you have written down. One way to back up KMS is to place the KMS information on a separate CD, DVD, or USB drive.
