Description: RBD snapshots are a fundamental feature in distributed storage systems that allow users to create time-stamped copies of block images, meaning that the state of a data block can be captured at a specific moment. This functionality is crucial for data management, as it provides an efficient way to perform backups and disaster recovery. Snapshots are lightweight and quick to create, as they do not duplicate existing data but rather record the differences since the last snapshot. This allows system administrators and end-users to restore data to a previous state without the need for full copies, saving time and storage space. Additionally, snapshots can be used in development and testing environments, allowing developers to experiment without the risk of losing important data. In summary, RBD snapshots are a powerful tool for data management in distributed storage ecosystems, offering flexibility and efficiency in storage administration.
