ChatGPT is _not_ a reliable source of information. Do not treat it as
a source of truthful statements.
If there is a way to back up VMs through virt-manager, I haven't found
it in my usage. Admittedly, I use ZFS snapshots for when I need to
roll back a VM disk image, which has happened rarely.

I haven't looked at the page you link to, but yes, a disk image backup
of some kind plus a XML dump of the virtual machine ("domain" in
libvirt/KVM parlace) will allow you to recreate the VM to that point
in time. You can also clone VMs.
