Hi guys, I have a CentOS system with virt-manager installed on it, the system is installed on a LVM partition with one PV for swap and one for "/", I only use KVM and qemu virtual machine on this server, I want to do a backup from my Virtual Machines on this server should I use LVM backup or an other stuff to do these backups ? what should I do ? stopping all VM before backup (I think) then do a LVM backup
all help is appreciated
