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. NovaStor 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.
