Data Protection Manager for System Center 2012 provides significant performance improvement for backup and more flexibility in recovery for Hyper-V deployments.

Hyper-V Express Full Backup: DPM 2012 has made significant improvement in Stand Alone Hyper-V backup performance by extending the Change Block Tracking for the Hyper-v on a standalone installation workload.  With Change Block Tracking, DPM transfers only the changed blocks to DPM server rather than reading the complete VHD files to find the changed blocks.  Apart from improving the backup performance (and so allowing admins to have more RPOs), the enhancement improves the overall Hyper-V server performance by reducing the number of IOs required for a backup. 

Hyper-V ILR option when DPM installed on a Guest:  Ability to recover only “required” files off of a backed up virtual machine is one of most sought after feature (called ILR) in Hyper-V Workloads of DPM.  With DPM 2010, customers were able to do ILR when DPM installed on a physical machine.  As virtualization is getting more and more prominent in enterprise deployments, DPM customers have been looking for ways to deploy DPM on a guest OS.  With DPM 2012, DPM 2012 deployment on a guest will also be able to provide Hyper-V ILR feature.  Also, the ILR can now be used in more scenarios of DPM physical deployments. 

 

The following matrix captures the enhancements and difference between DPM 2010 and DPM 2012.

  • Can I take incremental backup of Hyper-V virtual machines using DPM 2010 or DPM 2012?

    Thanks

  • Does DPM 2012 track migrations? In other words, after migrating a VM to another server will it still be protected on the new server?

  • as a side note, you should really spell out abbreviations before using them. true its a technical blog but still for ppl new  and learning about DPM 2012 some "dummies" content is appreciated =)

  • Good to hear about the ILR. A welcome addition as we migrated from another product to DPM mainly due to our entirely HyperV based  infrastructure.

    Any chance we could have individual user mailbox recovery to PST without having to stump up for third party products? :)
