With DPM 2007 Feature Pack (KB949779), we have added support for media co-location. With this feature, you can achieve better tape utilization by co-locating data from multiple protection groups with similar retention range. This feature is disabled by default. You can use following PowerShell commands to enable and disable tape co-location.
Enable Tape co-location:
Set-DPMGlobalProperty -DpmServer <DPM Server Name> -OptimizeTapeUsage $true
Disable Tape co-location:
Set-DPMGlobalProperty -DpmServer <DPM Server Name> -OptimizeTapeUsage $false
You can verify the status of tape co-location feature (Enabled/Disabled) from Library Management tab of DPMUI.
The Feature Pack can be downloaded from following locations.
