    Hi

    Well i am confused.

    In one of the above post you mention the rman command
    crosscheck backup completed before sysdate

    shows the backup as expired But now you are saying the command does not return anything.

    This clearly means there is more than what meets the eyes.

    You ran some other commands in between like a rman delete command that deleted the backups from the rman catalog database.

    I am not sure what you did but if you need help like this remotely you need to be precise and post the entire sequence of commands you executed for us to help.

    You need to also consider buying disk space so you can store enough backups or start looking at a very good tape library that can manage your backups in accordance with your retention policy

    IMHO you need practice rman backups on a single instance database first in a test environment till you grasp the nuances of rman

    The crosscheck command should have worked for you

    Look here in the documentation

    http://download-uk.oracle.com/docs/c...yn21.htm#80887


    You can perform a small test your self to reproduce what you did liek this

    1)Backup database plus archivelog
    2)Make a copy of the backupset
    3)Delete the backupset using os commands
    4)run rman crosscheck command it should report the backup pieces as expired since they are no longer accessible from the place where rman thinks they should be
    5)move the backupsets to the smae place as before
    6)run rman crosscheck command rman should recognize the backup pieces and mark them available

    RMAN Configuration for 2 nodes RAC Database

    Hi,

    hrishy I typed the command wrongly as

    RMAN>crosscheck backup completed between 'sysdate' and 'sysdate-30';

    It should be

    RMAN>crosscheck backup completed between 'sysdate-30' and 'sysdate';

    as we are searching result from the previous 30 days to till date.

    So this is returning me correct output which shows backup files as expired.

    Sorry for inconvenience, hrishy I think you are very near to clear my problem as you have understood everything clearly from OS to database. Please help me.

    Regards,

    Hi

    Well now if you have restored the backupsets exactly at the same path from where you had deleted it then the crosscheck backup command should now find that the backupsets are available and should mark them as available

    What else do you need ?

    RMAN Configuration for 2 nodes RAC Database

    Hi,

    hrishy sorry to say that again we went back to initial stage. As I said initially that the latest backup sets/files are physically present on disk, I have not deleted them. Than why to restore them?

    Hi

    RMAN expects them to find at the same place where it previously backed them up.Now not finding it at the same place rman thinks that the backup has expired.

    Are these files at the same place where it was backed up
