CLI script: Create protection groups for Disk based backups

First published on TECHNET on Mar 18, 2008

The following script creates a protection group with disk based protection, for a simple folder. It can be easily extended to add more data sources of different kinds – like Microsoft Exchange, SQL, Sharepoint, System state or Virtual Servers. The Synchronization frequency and retention ranges etc. can be easily modified to suit your needs.  Also, since we are protecting a sub-folder in a volume, we are using the CalculateSize parameter in Get-DataSourceDiskAllocation, which would calculate the exact size needed for all the items in that folder. This is not needed when protecting an application like Exchange/SQL or protection the entire File system volume.

# To D2D create PG and do the initial replication


# This script is for creating Disk to Disk PG for File System

# Create a .ps1 file with this script and run under DPM Management Shell



# Customize these values as per your environment
