I am trying to implement RMAN disk backups. I have two servers db1 which is the database server and backup1 which is a media server and holds my recovery catalog. db1 has three 54G mount points; /u01, /u02, /u03. backup1 has one 256G mount point; /b01.

I want to backup to disk, but to backup1:/b01.

My rman script is:
Code:
{
   allocate channel d1 type disk;
   setlimit channel d1 kbytes 2097150 maxopenfiles 32 readrate 2000;
   backup full filesperset 6
      format '/b01/rmanback/df_t%t_s%s_p%p'
      database;
   release channel d1;
}
I run this script on backup1, expecting the backup to go to backup1:/b01. Instead, I get an error message stating
RMAN-10035: exception raised in RPC: ORA-19504: failed to create file '/b01/rmanback/df_t1_s1_p1'

If I NFS mount backup1:/b01 to db1:/b01, then it works.

Any suggestions?
