Choosing a Replica Creation Method

When you create a protection group, you must choose a method for creating the replicas for the

volumes included in the group. Replica creation involves copying all the data selected for

protection to the DPM server and then running synchronization with consistency check for each of

the replicas.

DPM can create the replicas automatically over the network, or you can create the replicas

manually by restoring the data from removable media such as tape. Automatic replica creation is

easier, but, depending on the size of the protected data and the speed of the network, manual

replica creation can be faster

On the Choose Replica Creation Method page, select when you want DPM to replicate your

data.

To choose a replica creation method

Select the Automatically option to have DPM replicate the data across the network. For

large replica creation jobs, you might want to schedule the job to run only during periods

of light network traffic.

• Select Now to have DPM immediately begin copying the data from the computers

you are protecting to the DPM server.

• Select Later to schedule the initial copy at a later time—most likely after business

hours.

• Select Manually to use tape, USB storage, or other portable media to transfer the

baseline data to the DPM server.

This is the preferred option when synchronizing large amounts of data across a slow

WAN connection for the first time. For more information about manual replica

creation, in the DPM 2007 Operations Guide, see "Creating Replicas Manually"

in Managing Performance

(http://go.microsoft.com/fwlink/?LinkId=91859).

If you choose manual replica creation, you must know the details of the source

(protected server) and the replica path (DPM server). It is critical that you retain the

same directory structure and properties such as time stamps and security

permissions for the data that you are protecting.

Optimizing Performance

DPM 2007 provides several methods you can use to modify protection workloads and optimize

performance. To optimize the performance of the protection group, on the Summary page, click

the optimize performance link to launch the Optimize Performance dialog box.
