Hello Eyal ,
can you give to us the release note where it's written that also
the node must be upgraded? I can't find it

Hi Francesco,
Thanks for sharing.
There was a release note specifically for that issue.
In order to use incremental backup in the 4.4.5 engine, the host must
be upgraded to 4.4.5 as well.
In 4.4.4 version, backup scratch disk created on the host local
storage, in 4.4.5 scratch disks created on
the shared storage where the backed-up disk resides.
There is a bug for this to fail the backup operation with more proper
error - https://bugzilla.redhat.com/1950467

Hi,
i upgraded one of the hosts where the backup failed because I
noticed that in the lasts deployed hosts the process was smooth
and without errors. Maybe the update of on of the following
packages (or others) fixed the issue:

I shutdown the vms and upgraded the host via engine (without
reboot). I hope the packages upgraded helped, not a simple vms reboot.
Is there any way to upgrade the hosts/ vdsm packages without
shutdown the vms? Migrating it's not an option sadly.
Regards,
Francesco

Hi all,
I use a custom python script for performing full and incremental backup on few
hundreds vms. I customized the example script
inhttps://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_vm.py
<https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_vm.py>.
Everything was working fine, but starting from a few days ago, some vms starts to fail the backup. I upgraded the engine (self-hosted) from
4.4.4 to 4.4.5 yesterday afternoon and today most of the vms failed the
incremental and full backup.
The error is triggered when trying to get the backp_service in the
following function:
```
def backup_disk(disk, backups_service, from_checkpoint_id):
# We need to set an array because backups_service.add need it
disks = []
disks.append(disk)
add_error = False
try:
backup = backups_service.add(
types.Backup(
disks=disks,
from_checkpoint_id=from_checkpoint_id
)
)
except Exception as e:
exception = str(e)
logging.error("error on backups_service.add, set backup object to
False. Error: {} ".format(exception))
add_error = True
backup = False
if not add_error:
backup_service = backups_service.backup_service(backup.id
<http://backup.id>)
logging.info <http://logging.info>("Backup phase:
{}".format(backup.phase))
while backup.phase != types.BackupPhase.READY:
time.sleep(1)
try:
backup = backup_service.get()
except sdk.NotFoundError:
logging.error("backup_service NotFoundError, set backup object
to False")
backup = False
break
if backup and backup.to_checkpoint_id is not None:
logging.info <http://logging.info>("Created checkpoint
{}".format(backup.to_checkpoint_id))
return backup
```
Here's the error in the engine logs.

It's a known bug in 4.4.4/4.4.5? Any suggestion?
