Abstract
In one example, a method for processing data includes receiving information that identifies an ad hoc group of size 'n' of files F. . . F, each file F including a respective file sequence S that includes K data segments. Next, each file sequence S is sampled to obtain a sequence SS of data segments from the file sequence S, and a non-random sampling of data segments is sampled from each sequence SS to obtain a set SSU of the sequence SS. The data segments of each set SSU are then sampled to obtain a sample subset SSUS of the set SSU, and a compression ratio is determined for each data segment in each sample subset SSUS. Finally, an average data compression Ris estimated and output for the files F in the group of size 'n', based on the compression ratios.
