I would like to know, which restoration method is fast.
1. Restoring from RMAN Full backup (or)
2. Restoring from RMAN Image copy
I have another question,
In Incremental merge backup, when we run the below command for the first time it will perform FULL backup (Image copy)
Code: Select all
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG "INCR_MERGE" DATABASE;
RECOVER COPY OF DATABASE WITH TAG "INCR_MERGE" ;
then the second day it will perform just incremental backup and the 3rd day it will merge the 2nd day backup with the Previous FULL backup and then perform incremental backup and the same will goes on everyday.
here my question is, will we have every day FULL backup + one Incremental backup (or) only FULL backup.
