[Samba] can samba keep uid/gid/permission on a per-file-base?

[peter pilsl]

Is there a trick to copy files via smbfs and keep uid/gid/permissions?

Usually uid/gid/permission of a transfered file depends on the uid used when mounting the remote share.  But maybe there is a trick/patch whatever ... 

background:

I'd like to use a linux-based NAS to backup loads of files *including their permissions and uid/gid*.  The NAS supports NFS (which can do what I want) but the NFS-connections breaks all the time.

So smbfs/cifs is my available option.

* I need to backup the files on a per-file-base (and not in a tar-container) to make the backup-files easily and fast accessible from any thinkable client.
* rsync via ssh would be my last option, but ssh has lot of overhead and invokes a key-managment-strategy for automatic backup

thnx,
