The FastBIT ™
Patching Process
A Deeper Look Into Our 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.
Applying this technology to the backup process will reduce the
use of communication lines, backup tapes, and physical storage,
all leading to one thing... Cost Savings! Reduce your costs
without sacrificing the integrity of your backups. Here's how
our FastBIT patching technology is applied to your backup
process.
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. DataStor is 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.
