    hi all,
    i need information on backing up materialized views, what are (if any) the things that i have to take into consideration when backing up materialized views?, i would be grateful if any of you provided me with a document that deals with this issue.

    Normal online/offline backup will back these up.
    Once you have eliminated all of the impossible,
    whatever remains however improbable,
    must be true.

    I am not aware of a special backup practice for materialized views. Their definition is still stored in the dictionary, the only difference is that they occupy a segment aswell, all of this data is in the tablespaces you backup.

    If you're really worried about this, test a backup/recovery.

    Normal backups of MVs is just fine. If they are not too big you may neglect the backups and just reconstruct them if something happens to the DBs. I usually have an ASCII file with the create statements of all MVs and use it in case of disaster.
