Oracle 9i, 10g, 11g RMAN Compression

Introduced in Oracle 9i, RMAN is comprehensive backup solution for Oracle platforms through to today’s 11g release.

These backups are written in an RMAN specific format and are managed and catalogued by RMAN. Often these backups can consume significant disk capacity and managing that capacity gets more difficult and tricky as data volumes grow.

HyperBac for Oracle integrates with your native RMAN processes and allows you to compress your backup sets by up to 90%. Equally as important, HyperBac for Oracle can reduce the time it takes to create these backups by up to 35%.

It’s as simple as changing the extension of the destination file.

Consider the following example without compression.

RUN {	
ALLOCATE CHANNEL d1 DEVICE TYPE disk
FORMAT = '/u01/rpprod1/backup/%U';
BACKUP DATAFILE '/u01/oracle/oradata/rpprod1/tools01.dbf';
}

To simply compress the above datafile backup using HyperBac for Oracle, the command changes as follows.

RUN {	
ALLOCATE CHANNEL d1 DEVICE TYPE disk
FORMAT = '/u01/rpprod1/backup/%U.HBC';
BACKUP DATAFILE '/u01/oracle/oradata/rpprod1/tools01.dbf';
}
