Loss of Hydraulic quantity: Approximately 1:40 hours into [the] flight we received an 'R HYD QTY' EICAS alert. Quantity showed .48 and continued to slowly decrease over the next hour. Went to the appropriate QRH checklist: only says 'quantity is low.' After consultation with [Operations] and [Maintenance Control] decided it was fine to continue to destination. When Right hydraulic system quantity got down to .07; we executed the 'Loss of System Pressure' checklist; before the low pressure EICAS message appeared; in order to preclude any overheat damage to the hydraulic pumps. This was also coordinated with [Maintenance Control]. Flight was continued to destination for an uneventful landing and taxi to the gate. Maintenance met the aircraft and confirmed hydraulic fluid streaming aft on right wing.
