Hello everyone,
Im looking for the best way to backup VM running in the Openstack.
For the moment, my idea is to recreate VM out of .yaml HOT template.
Is it possible in Openstack, to do backup like with libvirt - live disk backup with active blockcommit/snapshots?
eg.
virsh snapshot-create-as --domain vm_name snamshot_name --diskspec vda,file=/path/where/snapshot/to/be/stored/vm_snapshot.qcow2 --disk-only --atomic
If not, any hints what is the most common way to backup Openstack VMs (hypervisor: kvm) ?
Best regards,
czezz
