Rman backup compression

Did you know you can make your backup at least twice faster with a single line ?

Demo :


RMAN> backup as compressed backupset database;
Starting backup at 2013-06-05_13:08:01
...
Finished backup at 2013-06-05_13:13:59

6 minutes for a compressed backup on a NAS with 24 Channels and 100Gb of raw data. Not bad. But look at this !


RMAN> configure compression algorithm 'low';
new RMAN configuration parameters are successfully stored
RMAN> backup as compressed backupset database;
Starting backup at 2013-06-05_14:06:09
...
Finished backup at 2013-06-05_14:08:29
RMAN> configure compression algorithm clear;
RMAN configuration parameters are successfully reset to default value

By configuring this magic parameter, it is now more than twice faster ! This is incredible !

Go to your cashier and grab some coins to get this amazing advanced compression option !

  1. For my demo, 100Gb raw data gave me 20Gb with “low” compression and 15Gb with the default compression

    It is about the same price as Partitioning and yes you need EE. But its usage is not limited to rman.
