Dear All,
after some trying, my impression is that the following steps do work with plain
Centos 7:
virsh snapshot-create-as VM backsnap
qemu-img convert -f qcow2 -s backsnap -O qcow2 VM.img backup.img
virsh snapshot-delete VM backsnap
Am I on the right track with these commands?

Dear Paolo,
Thank you very much. To execute the backup, I run a script. For the machine in
question, it looks as follows:
#!/bin/bash
dt=`date +%y%m%d`
qemu-img snapshot -c gatewayb72 /kvm02/gatewayb72.img
qemu-img convert -f qcow2 -O qcow2 /kvm02/gatewayb72.img
/backup/gatewayb72$dt.img
qemu-
Yes! My level of knowledge is that one uses the qcow2 format in order to be
able to create live snapshots/backups. Otherwise one would tend to use the more
efficient raw format. Is this not correct and did I apply the backup mechanism
in the wrong way?
