Comments on Back Up LVM XEN Guest Containing LVs
Back Up LVM XEN Guest Containing LVs In my day-job all our Linux boxes (bar 3) are Xen VMs. I wanted a way to take a backup of these with out the risk of the files changing underneath. For performance reasons I am running all of them on Logical Volumes.Within these VMs the DomU OS is once again using LVM for various reasons. This does create some headaches for taking the backup.

Where you say:
"What we want to do though is get to the files in this snapshot. As the DomU is using LVM, this is unfortunately non-trivial."
I was just wondering why that is? Is it because the LV that has had the snapshot taken has been mounted within the VM?
I assumed the author is copy-pasting a discussion from a forum. http://forums.techarena.in/operating-systems/1157489.htm Why didn't he give any credit to the forum member(s) that give the solution? I personally haven't tried the solution though .. :D
Not sure - compare the dates of this post and the mentioned forum discussion..
Funny how an idiot like n4nd4r can even comment. What a tool. This article was posted long before the other thread hacked it. Do the other posters in your above mentioned "thread" give this guy his just dues? Perhaps its not such a really original schema for vm backups.
Sometimes I really just dislike most of the human manure that is around these days.
