FastBIT™ Patching Process
A Deeper Look Into The Technology
The FastBIT™ patching process is the core technology behind our
revolutionary program. 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.
| When our backup program encounters a file for the first time, it
compresses the file and sends it securely to the backup server. Once a
file has been compressed and sent to the server, never again will we
send that entire file to the server. All future changes to your files
will result in only the changes within the files being sent to the
server. When the changes are received by the server, they are applied to
your backup files creating a complete up-to-date copy of your file
system. As an optional service, your daily FastBIT Patch Backup files
can be stored separately on the server allowing the flexibility of
restoring any file(s) from your backup data as of any point in time.
If you're wondering about the reliability of the patching technology,
there's no need to wonder anymore. This technology is not new. It has
been the only choice for IBM, Microsoft, Novell, and many other hardware
and software companies needing to update commercially distributed
software. We are the first to tightly integrate this existing technology
into a high performance backup application. |

The FastBIT patching process manipulates files at the binary
level. This means it can process any file type without error. Different types of
files will yield different FastBIT patch sizes based on the binary organization
of the file. We provide some FastBIT patch statistics to illustrate this point
further.
