In an earlier post, I looked at using RMAN managed replication to make two copies of an RMAN backupset to two separate Data Domains.
In the post Replicating an RMAN Backupset with Data Domain and DD Boost I then restored the database from the secondary copy to demonstrate that RMAN managed replication could be a useful tool for DBAs to protect against data center failures.
In this example however, I am going to use Data Domain’s native Mtree replication instead of RMAN’s managed replication.
In this post, we are going to install the DD Boost module for Oracle RMAN.
In the previous post, Configuring DD Boost Replication for Oracle RMAN, we enabled DD Boost on the Data Domain and set up storage units that replicate automatically between sites.
In this post, we are going to install and configure the DD Boost for Oracle RMAN module so that our RMAN backups can leverage the performance benefits of DD Boost.
In this post, we are going to install the DD Boost module for Oracle RMAN.
DD Boost is an optional module that works with Data Domain and a number of applications and databases, including Oracle. DD Boost moves some of the sophisticated deduplication process from the Data Domain appliance to the database server, resulting in a dramatic reduction in network bandwidth and backup times.
A greater than fifty percent reduction in backup times for a full level zero RMAN backup is typical when switching to DD Boost although as always, your mileage may vary.
