I'm a big fan of MS DPM and have been using it for years.  The one place where it really suffers, though, is the management console.  Even in DPM 2010, there are very few things you can do in a batch sequence, which is a common need for DPM administrators.

From time to time, your server may get a large amount of inconsistent replicas.  This is usually due to something outside of DPM's control.  For example, one DPM server I manage is a VM.  If the host server suspends the VM, then resumes and the target server it was backing up before suspend is suddenly offline (such as during a reboot cycle from updates), you can get inconsistent replicas.  There are numerous other scenarios, but you get the drift.  When this happens, the management console forces you to right click on every single alert individually and select "Run a synchronization job with consistent check."  (You can also just wait for the next automatic consistency check interval, but that's not always ideal.)

Luckily, PowerShell provides a better way to kick off a manual consistency check.  Behold!  Here is my DPM PowerShell script that kicks off a consistency check on every inconsistent replica.  This is tested with DPM 2010, but should also work with DPM 2007.

$pg = Get-ProtectionGroup
foreach ($pgi in $pg) { $ds = get-datasource $pgi; foreach ($dsi in $ds) { if ($dsi.State -eq 'Invalid') { Start-DatasourceConsistencyCheck $dsi | out-null; $dsi.ProductionServerName + " :: " + $dsi.DisplayPath } } }

Enjoy!
