The FastBIT patching process is the core technology behind our speedy backup service. The patching process involves the comparison of two different versions of the same file and extracting the differences between the files. When the differences are extracted from the two files, they are saved into a new file and compressed into what is known as a Patch. The patch file is often 85% to 99.9% smaller than the file which the patch was extracted from originally.

In order to perform a FastBIT backup, the software has to backup the files 3 times: the first backup is a full, the next backup will perform an incremental, and the third performs the first FastBIT backup.
