DPM can backup a variety of workloads as SQL, SharePoint, Exchange, Hyper-V VMs, File Servers, among others. While doing so, DPM creates an initial replica of the data, and takes the following backups incrementally, optimizing Storage and Network resources. However, at times, due to the large size of the Data-source, the initial replication over the network may consume a lot of time and network resources. In such cases, it is suggested that the Initial Replica be created manually to save on these.
In this blog, our guest,
talks about how the initial replication can be performed with SC 2016 DPM with Modern Backup Storage.
With DPM 2016 we’ve changed the whole architecture how DPM stores its backup data. Our new storage model, called Modern Backup Storage (MBS), utilizes VHDX files to store its backup data and removed the use of physical disks, overallocation and the need of colocation of workloads.

Introducing DPM 2016 Modern Backup Storage
This redesign changed the procedure for manually creating initial replicas, also called pre-seeding or pre-staging, with DPM 2016 and MBS. In DPM 2016 we’re no longer creating “real” replica volumes that are always accessible.
If you select to create the initial replica manually, e.g. when your protected workload is only available through a small WAN link, you will need to perform some additional steps to mount the replica VHDX.
Here we’ll show you how to do this step-by-step:
When adding a new datasource to protection, select “Manually” in the “Choose Replica Creation Method” dialog in the create/modify Protection Group wizard.
This results in a new protected datasource with the status: Manual replica creation pending
To figure out the Replica Path select the datasource and click on “Click to view details” next to “Replica path”.
This opens a new dialog window “Details of Replica Path” where you’ll find the Source and Destination Path of your Datasource.
Copy the path and save it in a notepad. It’ll look like the following.
E:\ on DPM2016TP5-01.contoso.local C:\Program Files\Microsoft System Center 2016\DPM\DPM\Volumes\Replica\31d8e7d7-8aff-4d54-9a45-a2425986e24c\d6b82768-738a-4f4e-b878-bc34afe189ea\Full\E-Vol\
The first part of the copied string is the source. The second part, separated by a whitespace, is the destination. The destination contains the following information:
