Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.

By scanning a larger area than other compression techniques, it can find and compress more repeating patterns, and thus achieve very high compression ratios (see Figure 1).

The method of file compression this app uses is many times referred to as the “Black Hole” by developers because of its extremely high compression ratios and mega-fast decompression.
