I am impressed by your depth of knowledge in Chinese history and literature, and how you connect them with 21st century computer high technology.
The 'backup is dead' is a good catch phrase. One thing that we have pitched before is that the backup is a 'spare tire'. The 'spare tire' is usually put into truck of your car and never touch. But when one of your running tire is flat, you need to take the 'spare tire' out of your truck and mount it on the wheel. That is a lot of works and only the 'black hand'(specialized IT guy) can handle it.
Also, the 'spare tire' may not be good since you have not used it for a long time. In that case, the 'black hand' can not help.
On the other hand, the 'replication' is that both 'tires'(systems) are running at the same time, when one tire is flat, the other one takes over right away. No interrupt and no need for a 'black hand' to do the dirty work.

「備份已死」是一個響亮的口號。我曾經說過，備份是一個 “備胎”，“備胎” 通常放在你的卡車裡不去碰它。但是，當你在公路上爆胎的時候，你將 “備胎” 拿出來裝在輪胎的位置上，這裡有很多工作要做而且只有 “黑手” （專業 IT人）可以處理它。
此外，“備胎” 的狀況可能並不好，因為你有很長一段時間沒有碰過它。在這種情況下，“黑手” 也沒有辦法讓你的車子繼續上路。
另一方面，“複製” 是兩個 “輪胎” （系統）併在一起同時運行，當一個輪胎爆胎，另一個輪胎馬上接手，沒有中斷，也不需要 “黑手” 做骯髒的工作。
