rsyncでqcow2型式のKVMの仮想ディスクをコピーする時，普通に使う，<\/p>\n
rsync\u00a0 -artlvd\u00a0 \u3053\u3063\u3061\u00a0 \u3042\u3063\u3061<\/pre>\nでは，sparseイメージのままコピーしてくれないことを経験的に知っていました．まあ，ディスクのイメージをコピーするなんてことは日常的に行うのではありませんから，<\/p>\n
cp -rdvpu\u00a0 \u3053\u3063\u3061\u3000\u3042\u3063\u3061<\/pre>\nでやってきました．<\/p>\n
そうはいっても，rsyncを使いたいときもあります．そこで，ネット検索をすると，–sparse (-S)<\/strong>と–inplace<\/strong>オプションを使うが，両方同時には指定できないとほとんどのサイトに書いてあります．<\/p>\n
しかし，最新版のrsync 3.1.3<\/a>では，この制限がなくなりました1<\/a><\/sup>初出時からしばらく，バージョン番号が間違っていましたので，訂正いたしました^^;<\/span>2<\/a><\/sup>2020\/11\/21現在の最新版は，3.2.3です．<\/span>．<\/p>\n
rsync -artlvdS --inplace\u00a0 \u3053\u3063\u3061\u00a0 \u3042\u3063\u3061<\/pre>\nで行けます．<\/p>\n
ネット検索しても，古い情報（今となってはフェイクニュースと同じ）の方が大半だってところにネット検索（というかGoogle検索）の限界というか弊害を感じます．<\/p>\n","protected":false},"excerpt":{"rendered":"
