Linux (サーバー制作) : ４１：baculaで容量に余裕があるホストにリストアデーターを保存する
”バックアップ用のホストを作り直す”で何回も出てくるので、ここに方法を書く
もちろん baculaの設定は終わっていて、起動している。
bacula-dirが起動していないホストでも出来るみたいだが、やっていないのでbacula-dirが起動しているホスト（smb3) で作業をする。
例として、Clientの名前が web-fd、リストアしたいデーターが web-Rdata、余裕のあるホスト名が smb-fd とする。
# bconsole

リストアされたデーターをコピーするには
smb-fd(ホスト名smb3)ではsambaが起動しているので、保存された場所は（Where: /SmbData/kinryo/Restores/web-Rdata）は他のホストから参照が可能。
まずこのデーターをマウントする。
# mount.cifs //smb3.kinryokai.net/kinryo /test1 -o username=administrator
パスワードを聞かれる。/test1は作成して置く
ディレクトリを変更。
# cd /test1/Restores/web-Rdata
コピー先をマウント（例はLVMの領域）
# mount /dev/Data/Rdata /test2
/test2も作成して置く
# cp -pr ./ /test2
NFSでマウントする方法もある。ここを参照
