RMAN backup on local filesystem

Question

Hi Experts,
I have an RMAN script and i want to use this script to backup my database on my local filesystem.How can i do it ? What changes i need to make in the script?How can i sepcify the path where i want to backup it ?
Actually this script was taken for doing it on tape drive .
Please help me.
connect target rman/rman@RMAN;
run
{ allocate channel t1 type 'SBT_TAPE' parms
'ENV=(NSR_SERVER=,NSR_DATA_VOLUME_POOL=,NSR_CLIENT=)'
format '/%d_%u_%s_%p/';
backup incremental level 0 ( database filesperset 8 include current controlfile );
sql 'alter system archive log current';
backup archivelog all delete input filesperset 10;
THanks & Regards,
MB

as per oracle best practices, use default channels where possible, these makes management easy !
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rman_backup/%F';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rman_backup/d_%d_s_%s_p_%p_t_%t' MAXPIECESIZE 2048 M;
CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' MAXPIECESIZE 1536 M PARMS "ENV=(NB_ORA_CLIENT=topdb1,NB_ORA_SERV=ilsdb2)" FORMAT 'd_%d_s_%s_p_%p_t_%t';
in the following example using default settings, parrallelism is set to 4 using veritas backup
first I take a backup to tape, see how channels get allocated, then to disk, old channels are released and new allocated to disk, this kind of backup policy makes things easy to manage and run, as reccomended by oracle.
