Hi,
BMR backup is always a full backup each time, however, the way that VSS snapshots work, only blocks that are different in the .vhd will be copied to the recovery point volume as the .vhd is overwritten on the DPM replica volume. Depending
on the Role of the server, you can get away with fewer recovery points, so putting BMR in a separate PG will save you space in the long run. It's a combination of retention range, and backup frequency that will determine how much space is required
for the BMR backups.
