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.
