    RMAN partial backup

    Hi all,

    DB: 10.2.03
    O/S: RHEL 3

    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?

    Thanks in advance,
    Chucks

    You should be able to consider Restartable Backups.

    However, if it's taking that long, then if possible you should consider Making Split Mirror Backups with RMAN, Change Tracking or at the very least Incremental Backups
