+.Backup `mode` for VMs:
+
+`stop` mode::
+
+This first performns a clean shutdown of the VM to make sure it is
+stopped. It then starts the VM in suspended mode and uses the qemu
+backup feature to dump all data. If the VM was running, we start
+(resume) it immediately after starting the qemu backup task. This
+keeps the downtime as low as possible.
+
+`suspend` mode::
+
+This mode does not really make sense for qemu. Please use snapshot
+mode instead.
+
+`snapshot` mode::
+
+This mode simply starts a qemu live backup task. If the guest agent
+is enabled (`agent: 1`) and running, it calls 'guest-fsfreeze-freeze'
+and 'guest-fsfreeze-thaw' to improve consistency.
