You can use the save_as functionality [1] in order to get a Virtual Machine backup. If you run the following command $ onevm saveas <vm_id> <disk_id> <image_name> the specified Virtual Machine disk will be saved after a shut-down in the new image (image_name). On the other hand when you stop a Virtual Machine, a checkpoint is generated containing the VM state [2]. This checkpoint and the disks files, that you can find inside the VMDIR [3, 4], are used to restore the VM keeping its state. Moreover, we are improving the Image repository functionality, for upcoming releases, adding new features like snapshotting of running VMs. Regards.
