Configuring compression

Edit online

You can adjust the amount of data that is being sent to the IBM Storage Protect™ server by compressing zero-byte blocks (RL_COMPRESSION profile keyword).

Figure 1. Null Block Compression

The graphic shows that before data is sent for backup in any of the described ways, it is compressed. This compression decreases the amount of data that is being sent.

Data Protection for SAP can decrease the amount of data that is sent to the IBM Storage Protect server by compressing zero-byte blocks. Compression can increase the CPU load on the database server and can improve performance in situations when the network is at the point of constraint. Compression is most effective with database files that contain large portions of null blocks. See the description of the RL_COMPRESSION keyword, in the Profile parameter descriptions topic, for details on how to activate Data Protection for SAP compression.
