Is MS Server Deduplication supported in this scenario? RRS feed

  • Question

  • We have installed SC Data Protection Manager on a Server 2012r2 VM (name = DPMserver), running on a Server 2012r2 Hyper-V cluster. 

    We have a secondary data disk (VHDX) attached to this VM, which lives on a network share on a separate physical Server (name = StoreServer) running Server 2012r2.

    StoreServer has dedupe enable on the volume where the DPMserver's data VHD is stored.

    Is this scenario supported?

    If not, can we just put .VHDX as an exclusion in StoreServer's Dedupe settings to stop any issues being caused?

    Thanks for any assistance.

  • Hi John,

    Please read the following whitepaper on how to configure supported deduplication of DPM storage: Deduplicating DPM storage. It will help you make sure all the pre-reqs are in place!

  • Hi John,

    The Azure backup agent-service converts the deduplicated data to normal data when it prepares the backup operation. It then optimizes the data for backup, encrypts the data and then sends the encrypted data to the online backup service.

    So deduplicated data will not have any effect on your Azure backups but you can expect 30-40% compression benefits depending on the type of data being backed up.

  • Thanks Markus, that clears it up!

    Though it's not quite clear from the article, if having Dedupe enabled will have any effect on using Azure backups from within DPM?

    Thanks
