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, the image can not be explored, etc. So any workarounds for them? Besides, are there any tips available to save system administrator's time? In this talk we will describe and demonstrate the workarounds about breaking the limitations and the tips to save time in system administration.


Clonezilla is GPL software for system deployment and recovery. 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, flexible, 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. Besides, are there any tips available to save system administrator’s time? In this talk, We will present why there are such limitations, and the workarounds to break the limitations. Besides, the tips to save time in system administration will also be given.

    Project Clonezilla; National Center for High-Performance Computing, Taiwan


    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, free software cloning and imaging program. He is the project leader of the file system imaging tool “Partclone”, and the maintainer of GParted live. The project DRBL won first place in ‘Public Sector Applications’ category at the Free Software Contest in France in 2007. He was the Chair of the Board of Directors, SLAT (Software Liberty Association of Taiwan) from 2011 to 2015, and spends most of his time in the development of DRBL, Clonezilla and promoting the use of free software and high-performance computing.

    Thomas Tsai is a developer and associate researcher in Free Software Lab at National Center for High-Performance Computing, Taiwan. The Free Software Lab is focused on developing free software that can be used in the field of High Performance Computing (HPC). He wrote partclone which is tool to make partition as image with GPL license. With Steven Hsiau, Ceasar Sun, and Jazz Wang, we developed other free software “DRBL” and “Clonezilla”. He is main developer of “Tuxboot” and “PyDRBL”, the sub project of DRBL. Member of koha taiwan community, help libraries use the open source library system. Thomas will keep develop free software and promote everyone enjoy GNU/Linux.

    All Thomas joined projects:

    DRBL – Diskless Remote Boot in Linux Clonezilla – A free software disaster recovery, disk cloning and deployment solution. Partclone – Tool to make partition as image with GPL license. PyDRBL – DRBL GUI Tuxboot – The advanced clonezilla_live usb creator modify from Unetbootin KOHA – An open source library system. Cloudboot – Cloudboot is a service that allows a PC to boot from cloud resources.
