I have a centos 7 machine. on this machine I've created several VM's using ovirt. I want to create a backup that machine(all the vm's and the server itself). I know there are many way to backup a server, but I'm not sure what is the best practice for such a backup?

How is your machine setup? Do you keep the VM files on a separate partition? If so, you can back them up separately from the host OS. That would be preferable, to separate host OS from the guest VMs. – SPRBRN Nov 16 '15 at 10:55

If you're looking at cloning the disk , the best tool IMO would be dd. Just make sure you're booting from a live CD before running it since you shouldn't clone the disk while it's being used.
dd if=/dev/sdX of=/dev/sdY bs=32M
where if= is the disk that you'd like to clone and of= is the destination to which you'd like to save the backup to (could be a thumb drive,portable HDD etc)
