System Center 2012 Data Protection Manager
System Center 2012 Data Protection Manager, frequently referred to as DPM, is Microsoft's
third full release of data protection technology. It originally debuted in 2005. DPM is
different from traditional backup technologies because it provides near-continuous protection
of the data, where typical "backup" technologies merely grab a snapshot copy at a specific
point in time. Legacy backup software typically backs up data using one of the following
three configurations:
Full Backup This configuration makes a full copy of everything targeted at the time
the job is run.
Incremental Backup This configuration makes a copy of any file that has changed
since the last full or incremental backup.
Differential This configuration makes a copy of the files that have changed since
the last full backup.
DMP takes a different approach that gives it the ability to restore data to within 15 minutes.
DPM does this by protecting files at the byte-level. The deltas are then copied to a
secondary disk, which in turn is copied to another disk, tape, or cloud backup provider, as shown
in Figure 5-4.
DPM provides the best protection and most Microsoft-supportable restore scenarios from
disk, tape, and cloud, and in a scalable, amendable, and cost-effective way. It also provides
the capability to protect virtual machines in your IT environment, as well as the applications
running inside those VMs.
DPM leverages the Volume Shadow Service (VSS) API to intelligently access the data while
at rest or in use. It also integrates into existing ticketing and workflow systems, scales to
the largest enterprise sizes, and integrates tightly into the other System Center 2012
components. Most importantly, if there is a need to restore data in AD, SQL, or Exchange
onpremises, DPM can do so, thereby protecting the integrity and preserving continued access
to Office 365.
System Center 2012 Virtual Machine Manager
System Center 2012 Virtual Machine Manager is the third full release of Virtual Machine
Manager, a product that Microsoft debuted in 2007. Virtual Machine Manager, frequently
referred to as VMM, is the Microsoft System Center component for managing large
numbers of virtual machine host servers based on Microsoft Hyper-V, VMware’s ESX, or Citrix’s
