I’ve talked about DPM a lot lately and I still receive more questions like: “What is DPM?” and “What makes DPM so good?”. To me, DPM is the best backup solution for the Windows Platform. Period! DPM allows you to backup File Servers (even open files!), that’s easy, but it also allows you to backup Exchange Servers, SQL Servers, SharePoint Servers, Virtualized workloads, and desktops! DPM can even back up your mobile desktops.
Not only does it allow you to intelligently backup these workloads, but it does all of this without creating an outage to take these backups. DPM will make backups of your Exchange Servers, SQL Servers, SharePoint Servers, Virtualized workloads, File Servers, and desktops in real time without user interruption! Take note: virtualized workloads can be backed up in real time as long as the guest OS is VSS aware (Volume Snapshot Service). VSS is included in Windows Server 2003, Windows Server 2008 (and R2) as well as the Client OS’, Windows XP, Windows Vista, and Windows 7. These virtualized versions of Windows can be backed up in real time. Keep in mind that the Windows Client OS’ are the professional SKUs only. The home use SKU’s are not supported in a virtual environment.
For non-VSS aware OS’, the VM is paused while a snapshot backup is taken. Typically, this snapshot backup takes less than two minutes, but there is an outage while this snapshot is being taken. DPM can even allow you to backup an Exchange, SQL or SharePoint server within a VM. I just love this flexibility, because now you can backup (and restore) all of your important workloads seamlessly with one tool.
As you know, I love doing the “How to videos” so you can see our products in action. This time, instead of doing the video myself, I’m going to point you to a great video presented by Jason Buffington. Jason was one of our Technical Product Managers for DPM and does a great job of helping you understand the impact DPM can have on your backup needs.

until next time,
Any guide to estimate additional disk space required for the VSS snapshot where the VM or VHD are located ? Can a problem occur if the VHD is fixed and consumes the entire volume ? Does the VM Host need a default location that is ## big enough for the VSS to create a snapshot and queue writes ?
hi please send me soft were foc please please
To set the record straight here....Well, it is good until someone tries to use this during business hours against a SQL database. This will potentially cause users to lose their database connection. So really this article is doing a poor job portraying DPM as the end all be all. Please do NOT use this for backing up SQL during the day. Even after hours, most businesses have jobs running in SQL 24x7. SQL backup and other 3rd party tools are a FAR better solution than DPM.
We use DPM all day, every day on SQL databases. Exchange and SharePoint DBs too! No downtime has ever been experienced by any of our users. We run backups every hour on the hour during business hours. DPM has been great for us!
