I have just attempted to backup a 3TB database using:
BACKUP DURATION 24:00 PARTIAL MINIMIZE LOAD DATABASE FORMAT '/rmandir/for/backups';
Now the backup has finished as the 24 hrs have now passed. I checked:
RMAN> list backup of database;
This shows only some of the files but not all. So it seems as 24 hrs was not enought to backup the whole database. Now if I was to re-run the backup with the same commands as before:
1/ Will the first backup be consistent/usable?
2/ Will it backup all the files or only the ones not available to RMAN?
3/ Is re-running the whole backup with the duration clause the best way to get a usable backup?
