This error is not related to backup. Seems the VM is stopped and does
not have a correctly initialize cloud-init ISO.

Please can you try if it is possible to start this VM at all?

Hi there,

I have a test setup investigating the migration from oVirt to Proxmox 
which used to work nicely but now only creates single byte length 
entries on PBS datastores.

Firstly backup to a cephfs storage works as expected:

zstd --all 0 --storage cephfs01 --mailnotification always
INFO: starting new backup job: vzdump 100 --mode snapshot 
--mailnotification always --node hbase01 --storage cephfs01 --all 0 
--compress zstd

The target storage exists and is known to PVE.

Is this a problem introduced with an update of PBS?

I tried adding backup users to PBS and using API-tokens to no avail.

Both PVE and PBS are most uptodate (no-subscription)
