Shrinking the recovery point volume (optional):
8. In case the
Recovery Point Volume already increased and DPM is consuming a lot of storage
you can try the option of shrinking the recovery point volume using the below
steps:
a. Click on the Protection Tab
b. Right click on the Protection Group and select “Modify Disk Allocation”
c. Click on the Shrink link next to each Recovery Point Volume, it will display
the new size of the volume.
d. Click on OK it will open a new popup showing the progress of DPM Shrink
operation.
Note: Use the Shrink feature
judiciously, repeated small shrinks cause free space fragmentation and
increases the number of extents.
