Here is what I have done so far on mkbackup.py For anyone interested in knowing how this will be done.. I think I will use dump and restore to produce the Live images for now which will be limited to Ext2/3/4 but I am glad to hear suggestions about supporting other filesystems and or how to use any other tools.s This should be interesting to see how it works as a backup media. Being Live-runnable and installable later with much much easy using Anaconda. The file is available at this URL and one attached. The on online will be updated periodically. Then I'll attach it to the mailing list here periodically too. http://autopsy.liveprojects.info/scripts/mkbackup.py
