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.
