Compression decreases the size of data being transferred during replica creation and synchronization and allows more data throughput with less impact to network performance. However, this option adds to the CPU load on both the DPM server and the protected computers. The amount of compression and improvement on network performance depends on workload.
Compression is enabled at the protection group level and applies to replica creation, synchronization, and consistency check operations. Recovery jobs also use compression.
To enable on-the-wire compression
In DPM Administrator console, click Protection on the navigation bar.
In the Actions pane, click Optimize performance.
On the Network tab, check Enable on-the-wire compression.
To apply your changes, click OK.
