Re: incremental rman backup using image copy

>>

I read some documentation and did limited testing but sounds like we still can't backup the datafiles as it is. RMAN backups the datafile using it's own naming convention(format command) e.g. datafile users_01.dbf can not be backed up as users_01.dbf in backup destination. >> If you are not using FRA (Flash Recovery Area), it is very well possible to have the same name using the format with BACKUP AS .

BACKUP AS COPY DATAFILE 'user01.dbf' FORMAT 'user01.dbf';

Anil, just a though, why dont the client wants to have backupsets rather than image copies? I know that Oracle first perfers to the image copies compare to incremental or backupsets.

But, you know, image copy is just a block to block copy, no compression. It would take good considerable time to finish the backup.

10g RMAN has very rich features, like BTC, binary compression and etc.
