Beyond that, the big problem is that primary storage has a much lower percentage of duplicate data than backup data.
除此之外,最大的问题是,主存储上重复数据所占的比例要比备份数据要低得多。
There are two factors that affect ADC: a minimum (threshold) amount of data is available for sampling (ADC_THRESHOLD) and a minimum percentage of useful data in the sampling buffer (ADC_MINPCT).
有两个因素会影响adc:可用于抽样的最小(阈值)数据量(adc _ THRESHOLD)和抽样缓冲区中有用数据的最小百分比(adc_minpct)。
