警告：已将“111.222.33.40”（ECDSA）永久添加到已知主机列表中

当我运行 rsync 命令将一个目录从一台服务器复制到另一台服务器时，出现以下警告：警告：已将“111.222.33.40”（ECDSA）永久添加到已知主机列表中。命令如下：

rsync -avz /root/custom-scripts  [email protected]:/root/

为什么此命令会产生此警告？这到底意味着什么？

rsync正在使用，这是在以前没有遇到过远程主机时出现的ssh正常信息消息。来自：sshman ssh

 ssh automatically maintains and checks a database containing identifica‐
 tion for all hosts it has ever been used with.  Host keys are stored in
 ~/.ssh/known_hosts in the user's home directory.  Additionally, the file
 /etc/ssh/ssh_known_hosts is automatically checked for known hosts.  Any
 new hosts are automatically added to the user's file.  If a host's iden‐
 tification ever changes, ssh warns about this and disables password
 authentication to prevent server spoofing or man-in-the-middle attacks,
 which could otherwise be used to circumvent the encryption.
