Probably the easiest way is to export the VM as OVA. The OVA format is a single file which includes the entire VM image along with the config. You can import it back into oVirt easily as well. You can do this from the GUI on a running VM and export to OVA without bringing the VM down. The export process will handle the creation and deletion of the snapshot. You can export to OVA to a directory located on one of the hosts, this directory could be a NFS mount on an external storage server if you want. The problem with export to OVA is that you can't put it on a schedule and it is mostly a manual process. You can however initiate it with Ansible. A little while ago I actually wrote an ansible playbook to backup multiple VMs on a schedule. It was wrote for oVirt 4.3, I have not had to time to test it with 4.4 yet https://github.com/silverorange/ovirt_ansible_backup On Sat, Aug 29, 2020 at 10:14 AM Stefan Wolf <shb256@gmail.com> wrote:
Hello to all
I try to backup a normal VM. But It seems that I don't really understand the concept. At first I found the possibility to backup with the api https://www.ovirt.org/documentation/administration_guide/#Setting_a_storage_... . Create a snapshot of the VM, finding the ID of the snapshot and the configuration of the VM makes sense to me. But at this point, I would download the config an the snapshot and put it to my backup storage. And not create a new VM attach the disk and run a backup with backup programm. And for restoring do the sam way backwards.
If i look at other project, there seems do be a way to download the snapshot and configfile, or am I wrong? Maybe someone can explain to me why I should use additional software to install in an additional machine. Or even better someone can explain to me how I don't have to use additional backup software.
Export the new virtual machine to a backup domain. See Exporting a Virtual Machine to a Data Domain in the Virtual Machine Management Guide. Sadly there is just writen what to do, not how, the link points to 404
And to the same topic backup. There is in the documentation the possibility to set up a backup storage It is nearly the same, create a snapshot, or clone the machine and export it to backup storage page. maybe someone can explain to me how to use backup storage
thank you very much
