In addition to backing up the target database with your normal backup software, I suggest keeping a second copy of the data in plain text. 除了用常规备份软件备份目标数据库外,我还建议再保存一份数据的纯文本副本。
Since the slave KDC is meant for backing up the master KDC in an emergency, the slave KDC might need to use the read-write copy. 因为从KDC用于在紧急情况下替代主KDC,所以从KDC可能需要使用可读写拷贝。
