We had an issue with DPM 2012 R2 UR7 that was released on July 28th, 2015. After installing UR7, expired recovery points on the disk were not getting cleaned up, causing an increase in DPM recovery point volume. The issue is fixed now with this re-release of UR7. Please install the update via Microsoft Update or download it via DPM 2012 R2 UR7 KB just like you install other DPM URs.
