<br># Usage Instructions:<br><br># Boot up your desktop/server with System Rescue CD version 1.3.2 for i386/amd64. <br># Then execute this backup script.

<br># FAQ<br># Q: Why do I want to write this cloning script when there are many open source cloning software available?<br># A: I am previously using Clonezilla. It is a very good cloning software. However, it could not detect all the<br>
# virtual machines in my LVM2 logical volumes and had to fall back on using dd to image all my domUs,<br># which resulted in an enormous 300 GB (!) backup image set and an extremely lengthy cloning process of <br># 7 hours. Clonezilla is very good for LVs which only contain filesystems, but not for LVs which contain<br>
# virtual machines with MBR, partition geometries and full fledged operating systems. It is very diffcult<br># to image nested logical volumes, i.e. logical volumes within logical volumes. And the PV within a LV is <br>
# the barrier. So it is not Clonezilla's fault. Anybody who knows how to activate all the logical volumes<br># of all the volume groups within LVM2 physical volumes inside a logical volume hosting a virtual machine,<br>
# please share your knowledge with me. Thank you very much.<br><br># No. of QC Checks Performed on this backup script: 1 <br><br>###############################################################################################################<br>

<br># The following 8 virtual machines have LVM2 physical volumes, so it is not possible to image using partimage <br># or fsarchiver directly, as both do not support PVs. The only convenient way is to image the logical volume <br>
# for the VM using dd, ie. sector by sector copy, and then piping it to gzip for a smaller backup image. <br># Other methods would have been more involved and tedious.<br><br># VM 1: Fedora 11 x86_64 PV domU (MPICH2 Virtual Supercomputer Center)<br>
