Hi, I don't think I will be using the LVM snapshot method. I will simply ensure that my domU is not running, then I proceed to do the losetup and kpartx procedure. Subsequently I will backup the MBR of my domU by dd-ing /dev/loopX and clone all the filesystems of the domU using fsarchiver.
I would like to use fsarchiver because it can support LZMA compression. LZMA can compress better than bzip2 and decompress 3x faster than bzip2. partimage only supports gzip and bzip2. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore My Primary Blog: http://teo-en-ming-aka-zhang-enming.blogspot.com My Secondary Blog: http://enmingteo.wordpress.com My Youtube videos: http://www.youtube.com/user/enmingteo Email: [email protected] Mobile Phone (Starhub Prepaid): +65-8369-2618 Street: Bedok Reservoir Road Country: Singapore On Thu, Nov 12, 2009 at 10:02 AM, Fajar A.
