Joe - Good point. I usually don't even consider offline RMAN backups. But for a really large database, that might be useful.

Since a noarchivelogmode database has to be shutdown, you'd be at a clean spot for recovery(and rman is smart enough to not let you do a backup with a shutdown abort as the last thing since the db has to be in mount state anyways), last i checked, its been about 6 months since i played with rman. joe original message below Hamid If you are thinking that incremental export would just export the > new rows in a table. It doesn't. It just detects tables that have changed since the last export and exports those tables. As Joe points out, RMAN can do incremental backups, but you must > have Enterprise Edition and run in archivelogmode. If you want just part of a table, you could do something better on your own. Since 8i export has a parameter QUERY. If you have a timestamp column for when a table is inserted or updated, then you could do a partial export of the table for just the new or changed rows. Again, I have done exports with the QUERY parameter, but haven't designed an incremental backup system based on that.
