Hi all,
I have set up RMAN Backup in my system which takes daily full backup as it is Standara Edition 9i.
My db size is 35GB.
As is see in the backup folder that there are three backup files each of 35GB.
I don't know why there are three peices.
I have given my RMAN Configuration below:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'H:\OCTO backup\%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 1;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'H:\OCTO backup\OCTO_%U';
CONFIGURE MAXSETSIZE TO UNLIMITED;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'H:\OCTO backup\SNCFOCTO.ORA';
Can Anybody explain me how come it take Three 35GB files. and why.
Thanks in Advance....
Elango

I guess it could be result from 'CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;'. Oracle would try to keep all info in recovery window, that means it would keep all in 7 days.
