Manually trigger a full sync by Clicking Start Full Sync

I deleted some rows in DB and the data in record type was not updated accordingly. 

I've checked the tab Sync Options in record type and there is a button Start Full Sync. I'm wondering if it will affect the DB when I click that button to sync data manually, as this record type is scheduled for full sync at another time, and I want my record type data to be updated immediately. 

Thanks for any advise!
