Disk2VHDスケジュールバックアップスクリプト

Disk2VHDを使用したこのような単純なバックアップスクリプトを使用しています。 Cディスクドライブの使用状況を確認してFドライブと比較するように少し変更したいので、Fに十分な空きディスク容量がない場合にのみ、古いイメージが削除されます。

現在、4つ以上がすでに作成されている場合、古いイメージが削除されます。

REM "DRIVES" can be one drive identifier with colon, multiple separated by spaces,
REM or asterisk for all.  
REM "DEST" can be a drive letter or a UNC.
