Description: A snapshot is a read-only copy of a Btrfs filesystem at a specific moment. This feature allows capturing the state of a filesystem at a given instant, facilitating data recovery and version management. Snapshots are lightweight and efficient, as they only store changes made after the snapshot was created, rather than duplicating all data. This results in optimized disk space usage and improved performance when performing backups. Additionally, snapshots can be used to revert the system to a previous state, which is useful in cases of system failure or user errors. In the context of containerization and virtualization, Btrfs snapshots integrate seamlessly with various management tools, allowing administrators to create more secure and flexible development and production environments. This functionality is particularly valuable in environments where stability and rapid recovery are critical, such as in servers and production systems. In summary, Btrfs snapshots are a powerful tool for data management, offering an efficient way to perform backups and maintain filesystem integrity.
