Unable to create daos on archive database

I enable the archive profile based on different server on a mail file with DAOS enable.

Exceuting load compact mail\mailfile.nsf -a I see the created file has DAOS disabled!

I try also to execute: load compact mail\mailfile.nsf -a -daos ON but… the archive are created without DAOS.

How can I create an archive file on different server with DAOS enable option?

thanks
