Database backup using RMAN

Question

Hello All,
I am new to RMAN.
I am trying to make some backups of my database using enterprise manager, so i choose to backup my database based on the Oracle-Suggested Backup schedule.
I got the below command from EM:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA_OEM_LEVEL_0';
backup incremental level 1 cumulative  copies=1 for recover of copy with tag 'ORA_OEM_LEVEL_0' database;
}i have the below question:
what does the above script do ? EM will create a job that will run it daily ? how can i check this job ? where is it logged?
where and how can i check the already configured channels ? for ex: channel oem_disk_backup
what does this script do ? recover copy of database with tag 'ORA_OEM_LEVEL_0' does it recover the database?
What are the RMAN scripts (run block), to backup my database once per week (for ex on Sunday)as level 0 backup and every day as incremental level 1 cumulative backup ? Since I think that the above script will run a level 0 backup once on the first execution and then the remaining backups are level 1 Incremental backups
Thanks and regards,

Since I think that the above script will run a level 0 backup once on the first execution and then the remaining backups are level 1 Incremental backupsYour script is doing a daily incremental updated backup. Every day, You are asking Oracle to update your image copy with latest changes of all redo as of yesterday. You are recovering your backup copies; see the following link;
