Media Co-location in DPM 2012

 

Media co-location has exist since DPM 2010. It allow you to group multiple protection group when in the same retention range into the same tape. In DPM 2010, this feature only can achieve using command-line (rather than GUI) and user cannot specify which protection group to be part of the tape co-location. A lot of customer has raised concern and mentioned that it is not efficient in term of tape usage. Below screenshot is showing backup of VMM data and each tape store few MB. This has resulted wastage of tape resources.
