Uncompressed Backup Problem in CIFS

[VDNKH]

I have a PROBLEM, i can do backup with compression lzo and gzip, but i cant with none compression, the vma format...
The Storage is a CIFS mounted in a local directory on the proxmox server, i add this backup storage as a directory on the web gui.
I do something wrong???

This is the log:
