Database Software

Hi,

I've an Oracle 10g database running on a Windows 2003 R2 server. On this server we have installed Microsoft Windows Services for Unix (MWSfU) which has a NFS client. With MWSfU we mount a filesystem on a Netapp. I can copy,change and delete files on the nfs share and in sqlplus I can spool files to the share. But when I try to make an rman backup on the share I get the following error:

rman target /

RMAN> backup as compressed backupset database format 'k:\aaa.bak';

I've also tried to use the UNC path:

The Oracle service is running on "LOCAL SYSTEM". Running the service under a domain account doesn't solve the problem.
I've read DocID 144485.1 but that workaround only work when using a Windows - Windows share.

Any suggestions?
