Choosing a Replica Creation Method

更新日期: 2010年4月

適用於: System Center Data Protection Manager 2010

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; however, 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

  1. 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, see Choosing a Replica Creation Method.

      Important重要事項
      If you choose manual replica creation, you must know the details of the data source (protected computer) 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.

  2. Click Next.
