コピーに使用する実マシンは，第2 Workstation（WS）の第2 OSであるDebianです．<\/p>\n\n\n\n

ディスクイメージは，今回update不能と判断したqcow2を使います．formatはしません．まるまるコピーするときはformatしたほうがあとのコピーが速いケースが多いですが，update不能なほど古いとはいえManjaro同士なので多少そのまま使えるファイルがあってコピーが早く済むかなと期待しました．<\/p>\n\n\n\n

実Manjaro (第2 WSの第1 OS）を念の為read onlyで，Debianにマウントし，仮想ディスクは，nbdのモジュールを使って，write enableでマウントしました．<\/p>\n\n\n\n

コピーはrsyncでします．<\/p>\n\n\n\n

実マシンのディスクスペースは400GBなのに対して仮想マシンは80GBしかないので，Raspberry Piのバックアップや，ISOファイルづくりの過程や完成品などはコピーしないよう，rsyncのフィルター設定をしました．<\/p>\n\n\n\n

途中でなんか余計なもののコピーを始めたら，とめて，フィルターを追加してまたコピーし直すというのができるのが，rsyncでするコピーの大きなメリットです．<\/p>\n\n\n\n

20分ほどでコピーが終わったので，\/etc\/fdiskを修正して今夜は終わりにします．<\/p>\n","protected":false},"excerpt":{"rendered":"
