Hacking Clonezilla!

Short Form


Clonezilla is popular for system deployment. However, there are some limitations. E.g. the destination partition must be equal or larger than the source one, software RAID/firmware RAID is not supported, or the image can not be explored. So any workarounds for them? In this talk we will describe and demonstrate the workarounds about breaking the limitations.


Clonezilla is GPL software for system deployment. It’s similar to Symantec Ghost or Acronis True Image. The file systems supported by Clonezilla are ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs of GNU/Linux, FAT, NTFS of MS Windows, HFS+ of Mac OS, UFS of FreeBSD, VMFS3 and VMFS5 of VMware ESX, and minix of Minix. Although Clonezilla is fast, powerful and reliable, it still has some limitations, e.g. the destination partition must be equal or larger than the source one, software RAID/firmware RAID is not supported, or the image can not be explored. In this talk, We will present why there are such limitations, and the workarounds to break the limitations.

    Steven Shiau is a researcher at the NCHC (National Center for High-performance Computing), Taiwan. While there he wrote parallel and distributed program to simulate plasma. This program formed the basic idea for the future development of the free software DRBL (Diskless Remote Boot in Linux), a rapid deployment software for distributed PC cluster and education environment. With Kuo-Lien Huang, Ceasar Sun, Jazz Wang and Thomas Tsai, he developed another free software “Clonezilla”, an open source clone system. He is the project leader of the file system imaging tool “Partclone”. He is also one of GParted developers, maintaining GParted live. The project DRBL won first place in ‘Public Sector Applications’ category at the Free Software Contest in France in 2007. He is the division leader of Software Technology Division at NCHC now, the Chair of the Board of Directors, SLAT (Software Liberty Association of Taiwan), and spends most of his time in the development of DRBL, Clonezilla and promoting the use of free software and high-performance computing.
