Hello! Someone has a backup system for backup VMs stored on lvm datastore (attached via iscsi to kvm nodes) for OpenNebula? Thanks! ---

Hello, there is this backup script, [Contribution: OpenNebula backup script for QCOW2 datastores](https://forum.opennebula.io/t/contribution-opennebula-backup-script-for-qcow2-datastores/5368), but actually without LVM support, but can be extended to support LVM. It uses external snapshots with block commit, so can be used also for VMs using block devices. [https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit](https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit) after creating snapshot you can just dd if=/path/to/lvm/image of=/path/to/backup/file after it you blockcommit external snapshot back to the original vm image. ---
