Today is the 40th anniversary of the first Moon landing on 20 July 1969. The Apollo 11 landing and Neil Armstrong’s first steps were watched by more than half a billion people worldwide.
今天是1969年7月20日第一次登月的40周年纪念日。全世界超过五亿人口都在观看阿波罗11号登陆和尼尔·阿姆斯特朗的第一步。
To celebrate, NASA has released digitally-remastered videos of the momentous event. They have also admitted to making a monumental mistake: the original high-resolution videos of the first moon walk have probably been erased forever.
为了庆祝这一点， 美国宇航局发布了该重大事件的数字化录像带 。 他们还承认犯了一个重大错误：第一次月球漫步的原始高分辨率视频可能已被永久删除。
All that remains are the poor-quality television broadcast videos. These were captured by a camera pointed at a wall monitor at mission control, Houston. The original two hours of data was stored on 45 one-inch telemetry tapes, but a four-year search for the archives has been unsuccessful. NASA suspects that the tapes have been lost forever and were probably recycled. In the 70’s and 80’s, it was common practice to overwrite old tapes with electronic output from orbiting satellites.
剩下的就是劣质的电视广播视频。 这些是由指向休斯顿任务控制处墙上监视器的摄像机捕获的。 最初的两个小时的数据存储在45个1英寸的遥测磁带上，但是对档案的四年搜索一直没有成功。 NASA怀疑这些磁带已经永久丢失，可能已经被回收了。 在70年代和80年代，通常的做法是用轨道卫星的电子输出覆盖旧磁带。
I’m sure the conspiracy theorists will find this all very convenient and further proof that we never reached the moon in the first place!
我敢肯定，阴谋论者会发现这一切非常方便，这进一步证明了我们从来没有到达月球！
But this is a valuable lesson for us all. None of us could admit to having data as valuable as the moon landing videos, but it’s easy to underestimate what data you have and the consequences of losing it. Your clients depend on your technical expertise: how will it look when you lose their information because you did not have a backup plan?
但这对我们所有人都是宝贵的教训。 我们谁都不会承认拥有与登月视频一样有价值的数据，但是很容易低估您拥有的数据以及丢失数据的后果。 客户取决于您的技术专长：由于没有备份计划而丢失他们的信息时，情况会如何？
Have you ever lost client data? How did you explain the situation?
您是否曾经丢失客户端数据？ 您是如何解释这种情况的？
