Backup size difference RMAN prompt vs Dataprotector with Oracle integration

edited Dec 24, 2014 10:03AM in Database Backup and Recovery (MOSC) 3 commentsAnswered

I did some backup-restore tests for performance en diskspace.


When I do a DP full backup to disk (same host as the DB) it give me a total backup size of approx. 200gb in 35 minutes

The same DB on the prompt with rman  (rman > connect target, etc..) gives me a backupfile of 57gb in 9 minutes.


What's happening here?


The rman backup:

DB size approx. 200gb

Device type to a disk location (same as host DB)

Configured 8 channels

RmanCommand> backup database;

Total duration: 9 minutes

Backup size in targetdir: 57 gb

In Dataprotecor I tried to imitate the same criteria as above…

DB size approx. 200gb (same db/host as above of course)

Howdy, Stranger!
