Would someone please be so kind to provide information, if KVM VM live backup is practically possible? If so, a tutorial would be phantastic.
For KVM, the libvirt middleware describes this process as follows: https://libvirt.org/kbase/live_full_disk_backup.html
TrueNAS SCALE Bluefin seems to include libvirt 7.0.0, so the "pull" method would apply. Under plain, debian systems, this is fully reliable.
However, this implies using the qcow2 file format. Unfortunately, TrueNAS does not seem to be geared towards implementing the qcwo2 file format (https://www.truenas.com/community/threads/advanced-vm-configuration-editing.90257/post-681611).
Quite obviously, one would want a consistent file image of each VMs disk created without stopping the VM which can be stored and copied to any file system. As much an one can bring in disk images from outside systems (https://www.truenas.com/community/t...-qcow2-format-truenas-scale.94609/post-739289), one should also be able to migrate them out.
Is this possible under current TrueNAS SCALE Bluefin and if so, how?
