返回信息流一个500GB的存储盘正异步复制到远端的站点，源与目标存储器每6小时同步一次。某一次源存储器在同步后4小时忽然失效，需要3小时才能从复制站恢复过来。求问在这次事件中，共损失了多少数据时间？
附原题:A 500 GB LUN is asynchronously replicated to a remote site. The source and the target LUNs are resynchronized every six hours. Recently the source LUN failed four hours after resynchronization, it took three hours to recover the data from the replica.
How much data loss occurred because of this event?
