Subject: [User Question] How to create a backup of an LVM based maschine without wasting space
Date: Fri, 12 Oct 2012 08:52:32 +0200	[thread overview]
Message-ID: <5077BE30.5010209@laukamp.me> (raw)

Hey all,

I have a simple user question. I have a few LVM based KVM guests and 
wan't to backup them to files. The simple and nasty way would be to 
create a complete output file with dd, which wastes very much space. So 
I would like to create a backup of the LVM to a file which only locates 
the space which is used on the LVM. Would be create when the output file 
would be something like a qcow2 file which could be also simply startet 
with KVM.

Is this supported by qemu_backup or what would be the best way to do this?

PS: Sorry for my bed english

Best Regards
