rsyncをcronで定期的に実行して、サーバー間のファイル同期する方法でも問題ないが、
ファイル送信元のデータが変更されたら出来るだけ迅速に送信先にもデータが同期されるように
しておきたい場合はGoogleからダウンロード出来るlsyncdを利用してファイル同期するという
選択肢があっても良いかもしれません。
CRONで直接rsyncを実行する場合の例）
rsync -av /home/sync_user/lsync/ sync_user@home002:/home/sync_user/lsync/
システム環境
|– HOME001:/home/sync_user/lsync/ (同期元）
|– lsyncd_test002:/home/sync_user/lsync/（同期先）

Summary : Inetd に代わる安全なデーモン
Description :
インターネットサービスデーモン inetd の代わりに Xinetd を使用しても安全
です。Xinetd はリモートホストのアドレスやアクセスの時刻に基づいてすべ
てのサービスに対するアクセス制御を行います。またアクセス拒否型攻撃を防
御することができます。Xinetd は、豊富なロギング機能を提供
します。サーバー引数の数に制限がなくホストマシン上の特定サービスと特定
IP アドレスをバインドすることができます。各サービスは各々独自の設定
ファイルを持ち、それらは /etc/xinetd.d ディレクトリに置かれます。
