SSHは正常に機能しますが、SCPプールを実行できません。

2 つのサーバー間で鍵認証を設定し、鍵なしで SSH で接続できます。たとえば、次のようになります。

ssh backup@hostname

これはうまく機能し、ログインします。ただし、SCPを使用してファイルを抽出しようとすると、ファイルは受信されません。

ターゲットファイルはchmod 777問題を解決するためにそのファイルを処理しましたが、コピーするファイルがあるにもかかわらず見つからないようです。

これはipの（難読化された）出力です。

scp -vvv backup@hostname:/var/stuff/backups/*.tgz /data/backups/

検証から始めてください。
