This error is expected if you don't have space to write the data.
ok.

This looks like a bug in the backup script - the backup should be finalized
even if the image transfer failed, but the error you get say the vm is
still
in backup mode.

1. Stop the current backup
If you still have the output from the command, we log the backup UUID.
If you lost the backup id, you can get it using the API - visit this
address in your browser:
https://myengine/ovirt-engine/api/vms/{vm-id}/backups/
Then stop the current backup using:
/usr/share/doc/python3-ovirt-engine-sdk4/examples/backup_vm.py stop
vm-id backup-id
If stopping the backup failed, stopping the VM will stop the backup.
I hope you are running recent enough version, since in early versions there
was a bug when you cannot stop the vm during a backup.
It is the latest 4.4.7. I run the backup_vm.py script from the engine:
ovirt-engine-4.4.7.7-1.el8.noarch
ovirt-engine-setup-plugin-imageio-4.4.7.7-1.el8.noarch
ovirt-imageio-common-2.2.0-1.el8.x86_64
ovirt-imageio-client-2.2.0-1.el8.x86_64
ovirt-imageio-daemon-2.2.0-1.el8.x86_64
python3-ovirt-engine-sdk4-4.4.13-1.el8.x86_64
But if I try the stop command I get the error
[g.cecchi@ovmgr1 ~]$ python3
/usr/share/doc/python3-ovirt-engine-sdk4/examples/backup_vm.py -c ovmgr1
stop dc386237-1e98-40c8-9d3d-45658163d1e2

2. File a bug about this
Filed this one, hope its is correct; I chose ovirt-imageio as the product
and Client as the component:
https://bugzilla.redhat.com/show_bug.cgi?id=2001136
I put information also about the error received with the stop command

ovirt.conf do not include the backup dir, only details about engine.
Adding backup-dir
to ovirt.conf or to backup specific configuration sounds like a good idea.
Nir
I agree
