## Summary
ZFS+ is a file system based on the ZFS platform, featuring proprietary data de-duplication technology extensions. These extensions were developed by the company GreenBytes. The file system is also known by the alias GBFS.

## Key Facts
- **Classification**: Instance of a file system
- **Core Technology**: Based on the ZFS file system
- **Primary Feature**: Proprietary data de-duplication technology
- **Extensions Developer**: The proprietary extensions were created by GreenBytes
- **Original Developer**: The underlying ZFS was developed by Sun Microsystems
- **Alias**: Also known as GBFS

## FAQs
### Q: What is the main difference between ZFS and ZFS+?
A: The primary difference is that ZFS+ includes proprietary data de-duplication technology extensions developed by GreenBytes. The core of ZFS+ is the ZFS file system, but the "+" signifies these specific, added features.

### Q: Who created ZFS+?
A: The development was a multi-stage process. The original ZFS file system was created by Sun Microsystems. The company GreenBytes later developed the proprietary extensions that define ZFS+.

### Q: Is ZFS+ known by other names?
A: Yes, ZFS+ is also known by the alias GBFS.

## Why It Matters
ZFS+ is significant because it represents a commercial enhancement of a well-regarded file system. By adding proprietary data de-duplication technology to the existing ZFS framework, GreenBytes aimed to create a more storage-efficient solution. Data de-duplication is a critical technology for reducing storage costs and capacity requirements by eliminating redundant data.

The existence of ZFS+ highlights a common business model in the software industry: building value-added, proprietary features on top of a powerful, often open-source, foundation. It demonstrates how a base technology like ZFS can be adapted and specialized to meet specific market demands, in this case, the need for advanced storage optimization. This approach allows companies to create competitive products without having to develop an entire file system from scratch.

## Notable For
- **Proprietary Extensions**: Its defining characteristic is the addition of proprietary extensions by GreenBytes to the base ZFS file system.
- **Focus on De-duplication**: The system is specifically known for its proprietary data de-duplication technology, a key feature for storage efficiency.
- **Hybrid Origin**: ZFS+ is a product built upon technology from a different creator; GreenBytes developed the extensions for the ZFS file system originally created by Sun Microsystems.
- **Distinct Alias**: It is also known by the alias GBFS, which likely stands for GreenBytes File System.

## Body
### Definition and Classification
ZFS+ is classified as a file system. It is a specific implementation or version of ZFS, which provides a format for storing and organizing files on a data storage device.

### Development and Technology
The core of ZFS+ is the ZFS file system, which was originally developed by Sun Microsystems. The distinguishing features of ZFS+ come from proprietary extensions that were developed by the company GreenBytes.

The key technology added by these extensions is data de-duplication. This feature is designed to reduce the amount of physical storage space required by eliminating redundant copies of data. This de-duplication technology within ZFS+ is proprietary to GreenBytes.

### Naming and Aliases
The name "ZFS+" indicates its origin as an extension of the ZFS file system. The system is also known by the alias **GBFS**.
