How to duplex archive logs in RAC DB?

Question

Hi
I need to set up alternative, local disk location for archive logs for both RAC nodes, outside ASM.
The reason behind it is to transfer the logs (along with full backups) to remote location to ensure security of data.
I have mapped same remote directory as R: drive on both nodes.
11.2.0.2 RAC Standard 2-nodes database
Windows 2008 R2 Standard
+DATA ASM Storage
SYS@proton2x1> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1750
Next log sequence to archive 1752
Current log sequence 1752
SYS@proton2x1> show parameter recov
NAME TYPE VALUE
db_recovery_file_dest string +DATA
The problem is when I set duplex location:
SQL> alter system set log_archive_duplex_dest='LOCATION=R:' SCOPE=spfile;
restart nodes and switch online logs 3 times it hangs and no archiive logs are written in R:\ directory.
alert log says:
LGWR: Error 16017 validating archivelog destination information
I played in similar way with other parameters:
alter system set log_archive_dest_1='LOCATION=+DATA MANDATORY' SCOPE=spfile;
alter system set log_archive_dest_2='LOCATION=R: OPTIONAL' SCOPE=spfile;
with same issue.
The question is, how to set up second location for archivelogs, outside ASM storage?
or maybe someone has another idea how to transfer/copy archivelogs to a remote storage?
I though about 'cp' command on asmcmd tool but it would be hard to sync source and target locations.

I tested the hint no.1 it before, now I've done it again to show the output:
SYS@vip2x> alter system set log_archive_dest_2='LOCATION=R:\archive';
it gives these errors:
ORA-16032: parameter LOG_ARCHIVE_DEST_2 destination string cannot be translated
ORA-09291: sksachk: invalid device specified for archive destination
OSD-04018: Unable to access the specified directory or device.
O/S-Error: (OS 3) The system cannot find the path specified.This maybe OS error that oracle cannot access it, Is this mounted properly?

I tried also the other way (hint no.2), but got stuck as well:
SYS@proton2x1> alter system set log_archive_dest='LOCATION=+DATA';
alter system set log_archive_dest='LOCATION=+DATA'
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16018: cannot use LOG_ARCHIVE_DEST with LOG_ARCHIVE_DEST_n or DB_RECOVERY_FILE_DEST
Dont specify LOCATION in log_archive_dest
SYS@proton2x1> alter system set log_archive_duplex_dest='LOCATION=R:';
alter system set log_archive_duplex_dest='LOCATION=R:'
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16018: cannot use LOG_ARCHIVE_DUPLEX_DEST with LOG_ARCHIVE_DEST_n or DB_RECOVERY_FILE_DEST
Again dont use LOCATION in LOG_ARCHIVE_DUPLEX_DEST

I don't want to change DB_RECOVERY_FILE_DEST.
So I assume I need to follow hint no.1 but why is this?:
SYS@proton2x1> alter system set log_archive_dest_2='LOCATION=R:\archive';
alter system set log_archive_dest_2='LOCATION=R:\archive'
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16032: parameter LOG_ARCHIVE_DEST_2 destination string cannot be translated
ORA-09291: sksachk: invalid device specified for archive destination
OSD-04018: Unable to access the specified directory or device.
O/S-Error: (OS 3) The system cannot find the path specified.See my example:
SQL> alter system set log_archive_dest_1='LOCATION=D:\app\rnagi\archive' scope=spfile;
System altered.
SQL> alter system set log_archive_dest_2='LOCATION=D:\app\rnagi\archive2' scope=spfile;
System altered.Or use
SQL> alter system set log_archive_dest='D:\app\rnagi\archive' scope=spfile;
System altered.
SQL> alter system set log_archive_duplex_dest='D:\app\rnagi\archive2' scope=spfile;
System altered.
