Clonezilla

Clonezilla は、True Image®に似た、パーティションおよびディスククローンツールです。 これは、ハードドライブにのみ使用されているブロックを保存し、復元します。 Clonezillaは、次の2種類、Clonezilla LiveとClonezilla SE（サーバー版）をご利用いただけます。

• Filesystem supported: ext2, ext3, ext4, reiserfs, xfs, jfs of GNU/Linux, FAT, NTFS of MS Windows, HFS+ of Mac OS, UFS of BSD, minix of Minix and VMFS of VMWare ESX. Therefore you can clone GNU/Linux, MS windows and Intel-based Mac OS, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla
• LVM2 (LVM version 1 is not) under GNU/Linux is supported.
• Multicast is supported in Clonezilla SE, which is suitable for massively clone.
