RMAN - solid backup

This isn't the Oracle Suggested Backup script, but this is my RMAN script for a good, solid RMAN backup. It will need slight tweaking if you decide to use it.

backup check logical database; 

sql 'alter system archive log current'; 

backup archivelog all delete all input; 

 allocate channel for maintenance device type disk; 

RUN {  

crosscheck backup of database; 

crosscheck backup of controlfile; 

crosscheck archivelog all;} 

delete force noprompt expired backup of database; 

delete force noprompt expired backup of controlfile; 

delete force noprompt expired archivelog all; 

delete force noprompt obsolete redundancy 5; 

sql "ALTER DATABASE BACKUP CONTROLFILE TO TRACE"; 

sql "ALTER DATABASE BACKUP CONTROLFILE TO ''D:\FRA\SBY01\SBY01_CONTROLFILE_BACKUP.CTL'' REUSE"; 

sql "CREATE PFILE=''C:\oracle\product\10.2.0\db_1\admin\SBY01\pfile\INITSBY01.INI'' FROM  SPFILE"; 

exit;
