他のサーバーをバックアップするバックアップサーバーがありますが、数日後にバックアップサーバーにエラーが発生し始めて回復することはできません。以下のエラーログが私ができるよりも問題をよりよく説明していると思います。

答え1
この問題が発生し始めた時点で、クライアントバックアップディレクトリのファイル数が大幅に増えましたか？情報
（信号= PIPEによって中断されました）
Unixパイプが思いますね。バックアップ命名法では、パイプはファイル名パイプである可能性があります。ファイル数が特定のバッファサイズ（サーバーとクライアントのシステムアーキテクチャを知らない場合は指定できません）を超えると、これらのエラーが発生する可能性があります。このエラーは、おなじみのバックアップアプリケーションで発生するため、メッセージとファイル数の間の相関関係を証明することはできませんが、確認に問題はありません。
この場合、回避策は完全にあなた次第です。古いファイルを削除するか、サブディレクトリを作成し、特定の数のファイルをそのディレクトリにプッシュしてディレクトリをクリーンアップします。または両方の組み合わせです。
幸運を祈る
