Use checkpoint feature along with Snapshots at slave side to make sure 
each days snapshot contains all the changes from that day.

When you set checkpoint, you can watch the status of checkpoint 
completion using geo-rep status. Once checkpoint complete, it is 
guaranteed that everything created before Checkpoint Time is synced to 
slave.(Note: It only ensures that all the creates/updates done before 
checkpoint time but Geo-rep may sync the files which are 
created/modified after Checkpoint time)
