私の質問に答えます。

使用 と 一部 の ハッキングunison後処理 ​




（（まだ災害復旧処理することが多いので、終わったと思います。）これ現在...))
]

そのため、別のコンピュータにあったSSDがあり、
それを小さなSATA-USBエンクロージャ/アダプタエンクロージャの1つに挿入して
外部データドライブとしてマウントし、ブートパーティションをこのコンピュータAディレクトリにコピーするために
使用しました。rsync -aAXバックアップのためにサーバーに

しかし、別の事件が起こった後おそらく元のブートパーティションの内容を変更せずに
2番目のバックアップを作成しました。

このコンピュータには2つのディレクトリがあります
。おそらくまったく同じバックアップのコピーが2つ
ありますが、確認したかったです。

だから私の質問は次のようになります
この2つの大規模バックアップディレクトリを比較/区別する最良の方法は何ですか？

検討/試行したが問題があるかどうかわからないことの概要：

  • diffそれ自体

  • rsync「空の状態で実行」技術

  • unison[（考えてみましたが、バックアップが大きすぎて既存のハードウェアが遅いため実行していません。）]

これらの1つは本質的に良い選択ですか？
それでは、どのように使用するのか詳細に修正がありますか？

それとも私が知る必要がある別の追加オプションがありますか？

私の試みと結果/問題の詳細：

diff

これを行うための確実な方法は」ノーマル 「ディレクトリは次のよう
にdiff -r dir_A dir_B
なり
ます 。diff -r --no-dereference dir_A dir_B
--no-dereference
漠然と過去にも同様の状況がありました。
)

しかし、それを使用する際の問題は、diffこれらのディレクトリがもちろん非常に大きくて
ブート可能なシステムの「奇妙な」ファイル
（「文字特殊ファイル」や「ブロック特殊ファイル」など）でいっぱいになっていることです。

rsync

rsyncそこで、その間に再度使用して、
変更が報告されたことを確認するために「テスト実行」を実行することを考えました。

いいね：
$sudo rsyncy -n -aAX dir_A dir_B --log-file=log_file

ところが突然そんな気がした。

  • 「あるならどうしよう？新しいファイルはdir_Bにありますか？ 」
  • 「rsyncyはこれを報告する必要がありますか？」


したがって、$sudo rsyncy -n -aAX --delete dir_A dir_B --log-file='log_file[A-to-B]'
と
$の両方を確認する必要があるようです。sudo rsyncy -n -aAX --delete dir_B dir_A --log-file='log_file[B-to-A]'
少し不気味な感じがし始めます。結局のところ、これは仕事に適したツールではないかもしれません...？

私がログファイルから読んだ内容は次のとおりです。

はい、もう一度rsyncこのヒントが実際に作業に適したツールなのかと思いますか？

たぶんそれは本当に正しい答えかもしれません。はい例：

unison

[まだわからない？ ]

答え1

unison

これはついに私のために働いた。

          test $size = "0"  
        or breakpoint  
      end  
  end
