一些 IT 专业人士认为，重复数据删除和单实例存储（SIS）是一回事，但其实并非如此。

Some IT professionals think that deduplication and Single Instance Store (SIS) are the same thing, but they are not.

我们还可以重复数据对象的属性。

We can also iterate over the properties of a data object.

不过，这种分割方式会创建重复数据。

However, this kind of shredding creates duplicate data.

So this is very similar, this is a kind of recursive thinking we talked about earlier, where we take our problem and we make it smaller we solve a smaller problem, et cetera.

我们则跳过比猜想数小的那个区间,然后我们重复这一过程,跟之前我们讲过的，递归思想非常类似,我们解决问题的时候,先把问题一步步变小，然后解决小问题。
