My vzdump task to SMB-NAS fails if uncompressed is selected. Switching to a compressed (zstd) dump works. Also an uncompressed vzdump to a NFS share on the same target machine works. Suspect it is something with the SMB share configuration - default done via the Datacenter Storage GUI. Also system log on source and target machine is "empty" in regards to the problem.
