FastBIT Patching Process
FastBIT is a NovaStor Technology



A Deeper Look Into The FastBIT™ 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.

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. Wild Blue Backup 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.
