Hot Backup Mannual Pls review for 9i

Question

Hi All,
I am a forms developer for 9 years and new to dba/backup. I have to review a mannual hot backup for a 9i database in Solaris.
There 2 scripts
1) Script to backup all data files (system, users...) runs once in a day and Ftp to a ftp server
2) Script which runs every one hour which takes a backup of redo log files, archive files and control file. And this is ftp to a ftp server.
Q1 Does this good enough to recover the data up to last one hour ?
Q2 Here is my Script 2. Is this correct?
sqlplus "/ as sysdba" << EOF
alter system switch logfile;
EOF
# Sleep for sometime, till the log file is complete
sleep 60
sqlplus "/ as sysdba" << EOF
! rm -Rf /backup/OHotBackup/XX/arch
alter database backup controlfile to '/backup/OHotBackup/XXctrl.ctl';
! cp -r /opt/oracle/product/9.2.0/dbs/arch /backup/OHotBackup/XX
! mv /backup/OHotBackup/XX/ctrl.ctl /backup/OHotBackup/XX/arch/ctrl.ctl
! cp -r /opt/oracle/product/9.2.0/oradata/XX/*.log /backup/XX/arch
! compress /backup/OHotBackup/XX/arch/*.*
! rm /backup/OHotBackup/XX/arch_files.tar
! tar -cvf /backup/OHotBackupXX/arch_files.tar /backup/OHotBackup/XX/arch
select to_char(sysdate,'mm-dd-yyyy:hh:mm:ss.ss') endtime from dual;
disconnect
exit
Thanks in Advance. I read that RMAN backup is better than mannual but for some reasons my company is using this script.

Hi Tom,
Thanks for the reply. First script backs up all the data files.
Here is the script.
PATH=$PATH:$ORACLE_HOME/bin
sqlplus "/as sysdba" << EOF
select to_char(sysdate,'mm-dd-yyyy:hh:mm:ss.ss') astarttime from dual;
SET TERMOUT OFF
SET FEEDBACK OFF
set serveroutput on
SPOOL /opt/oracle/admin/BackupScripts/CopyFiles.sql
declare
cursor c1 is
select distinct(tablespace_name)
from dba_data_files;
cursor c2(ts_name in varchar2) is
select file_name
from dba_data_files
where tablespace_name=ts_name;
data_rec dba_data_files.file_name%type;
ts_rec dba_data_files.tablespace_name%type;
begin
open c1;
loop
fetch c1 into ts_rec;
exit when c1%notfound;
dbms_output.put_line('alter tablespace '||ts_rec||' begin backup;');
open c2(ts_rec);
loop
fetch c2 into data_rec;
exit when c2%notfound;
dbms_output.put_line('!cp -p '||data_rec||' /backup/OHotBackup/OFDAP');
end loop;
close c2;
dbms_output.put_line('alter tablespace '||ts_rec||' end backup;');
end loop;
close c1;
dbms_output.put_line('ALTER SYSTEM ARCHIVE LOG CURRENT;');
dbms_output.put_line('!rm /backup/OHotBackup/OFDAP/ht.ctl');
dbms_output.put_line('alter database backup controlfile to ' || '''/backup/OHotBackup/OFDAP/ht.ctl'''||';');
dbms_output.put_line('alter database backup controlfile to trace;');
dbms_output.put_line('!rm /backup/OHotBackup/OFDAP/initOFDAP.ora');
dbms_output.put_line('!cp -p /opt/oracle/product/9.2.0/admin/OFDAP/pfile/initOFDAP.ora /backup/OHotBackup/OFDAP');
dbms_output.put_line('!rm /backup/OHotBackup/OFDAP/*.dbf.Z');
dbms_output.put_line('!compress /backup/OHotBackup/OFDAP/*.dbf');
end;
spool off;
!perl -pi -e 's/Statement processed.//g' /opt/oracle/admin/BackupScripts/CopyFiles.sql
@/opt/oracle/admin/BackupScripts/CopyFiles.sql
select to_char(sysdate,'mm-dd-yyyy:hh:mm:ss.ss') aendtime from dual;
disconnect
