RMAN incremental merge
Hi,
I am running Level 0 on Sunday and Level 1 on all week days.
LEVEL 0:
run {
backup archivelog all delete input;
BACKUP INCREMENTAL LEVEL 0 TAG=LEVEL_0 DATABASE;
}
LEVEL 1:
run {
backup archivelog all delete input;
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG LEVEL_0 DATABASE;
RECOVER COPY OF DATABASE WITH TAG LEVEL_0;
}
Questions: Here my Level 0 will create "backup set" instead of image copies of the db files.
When it's time to run LEVEL 1 with the incremental merge "FOR RECOVER OF COPY WITH TAG LEVEL_0", it will need image copies. Since they are not created, RMAN will create all image copies of LEVEL 0. The previously created "backup set" by my LEVEL 0 is useless for the use of "incremental merge" purpose.
