I am a new bie to RMAN concepts. I just went through basic concepts and tried to implement RMAN in one of my test server which is Oracle 9i.
I have given few configurations and executed the below command through RMAN prompt.
This backed up all .dbf files successfully but its consuming space.
So, i need to try Compressed RMAN concept. Please let me know if compressed backup is supported in Oracle 9i.
If yes, Kindly give me the basic command to implement.
I tried the below command. But its throwing error.
RMAN> BACKUP AS COMPRESSED BACKUPSET DATABASE;
Oracle 9i does not support compressed RMAN backups. It came in as a feature from 10g.
You can try zipping the backup pieces once the backup is completed in order to save the disk space.
If you feel that your question has been answered, then please consider closing your question by providing appropriate points.
Thanks for your response.
Is there any other option to reduce the size of the backup in Oracle 9i.
Doing a file system backup consumes 6.7 GB space but RMAN backup comsumes 17 GB space.
But the time it takes to backup through RMAN is reduced which is really excellent.
I would suggest you to refer documents
Oracle 11g: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmmaint.htm
