HAMMER

HAMMER is a file system specifically designed for the DragonFly BSD operating system. It focuses on high performance, reliability, and offers advanced data management capabilities. Key features of HAMMER include support for snapshots, replication, and efficient data management.

Key Characteristics of HAMMER

• Snapshots: HAMMER allows the creation of filesystem snapshots, enabling the preservation of the system's state at a specific point in time. This is useful for data backup and recovery.
• Copy-on-write: The file system employs a copy-on-write method, protecting data from loss during file modifications. Instead of altering the existing block, the system creates a new block with the changes, preventing data corruption.
• Replication: HAMMER supports data replication between multiple systems, allowing real-time synchronization of data. This is beneficial for creating fault-tolerant systems.
• Efficient Space Usage: The file system optimizes disk space utilization by storing only necessary data and minimizing duplication.
• Support for Large Files: HAMMER can effectively handle large files and data volumes, making it suitable for server and embedded applications.
• Data Access: HAMMER provides users with powerful tools for searching and accessing data, including the ability to restore data from snapshots.

Applications of HAMMER

• Servers: HAMMER is used on servers that require high performance and reliability, especially in scenarios involving large data volumes.
• Embedded Systems: Due to its efficiency and data backup capabilities, HAMMER is well-suited for embedded solutions.

The HAMMER file system is an essential part of DragonFly BSD, offering unique features that make it attractive for various applications requiring reliable data storage and management.
