Using On-the-Wire Compression
Compression decreases the size of data being transferred during replica creation and
synchronization, and it 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 for a protected computer and applies to replica creation,
synchronization, and consistency check operations. Recovery jobs also use compression.
To enable on-the-wire compression
1. In DPM Administrator Console, click Protection on the navigation bar.
2. In the Actions pane, click Optimize performance.
3. On the Network tab, select Enable on-the-wire compression.
4. To apply your changes, click OK.

Staggering Synchronization Start Times
You can specify the starting time, in minutes after the hour, of synchronization jobs for each
protection group. Staggered starting times minimize the network impact of running multiple large
protection jobs simultaneously.
To determine whether staggering the start times of synchronization jobs is appropriate for your
needs, first gather information about scheduled protection jobs in DPM Administrator Console:
• In the Monitoring task area, on the Jobs tab, review jobs that are scheduled for times when
the DPM server experiences large disk queues.
• In the Protection task area, review details for protection groups to determine the size and
frequency of protection jobs.
Offsetting synchronization start times can also be used to optimize secondary protection of
another DPM server. Secondary protection is when a DPM server protects the database and
replicas of another DPM server, referred to as the primary DPM server. You can offset the
synchronization of the primary DPM server to the secondary DPM server to occur after the data
sources are synchronized to the primary DPM server.
