| Macrium Reflect uses a very fast, real-time, *streaming block compression algorithm. This will not provide the same overall compression ratio as common compression utilities such a 7-Zip which use, much slower, whole file data compression techniques. *All 'mountable' backup files, such as those created by Macrium Reflect, require discreet discrete blocks of data to be compressed and decompressed 'on the fly'. This enables images and backup files to be incremented and mounted as drives in Windows Explorer, |

| ||
