Do we need to stop DPM backups when updating SP2013 with CU

Hi - planning to install the Dec14 CU and want to know if it is required to Stop DPM protection when running PSConfig?

Our DPM guy says DPM protection cannot be paused - only stopped and this would remove the Protection group completely and we would need to reconfigure afterwards. He thinks that because DPM bacup is different to SQL in that it only reads the T Logs to synchronize every 15min after the daly full backup at 8PM - so as long as we avoid running PSConfig when the full backup runs it should be no problem

I have always had SQL backups stopped when updating SharePoint - is the DPM guy right that I don't need to worry about DPM syncs?

Thanks
