Synology NAS to Synology NAS ABB question

I have 2 Synology NAS on a network, 3 total. My Synology01 is the primary NAS that I use for storage, virtualization, etc. The Synology02 is really only used to backup PCs and the Synology01 via ABB. My Synology02 is filling up with space and I would like to move all my PC backups to Synology01. Is there a way to do an ABB complete backup to Synology02 but minus any backups from the PCs?
