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:
root@hbase01 ~ # vzdump 100 --mode snapshot --node hbase01 --compress
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

Backup to a Proxmox Backup Server PBS fails though
root@hbase01 ~ # vzdump 100 --mode snapshot --node hbase01 --compress
zstd --all 0 --storage PVE-FE-3 --mailnotification always
INFO: starting new backup job: vzdump 100 --all 0 --node hbase01

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)
