Description: An LVM snapshot (Logical Volume Manager) is a point-in-time copy of a logical volume, allowing system administrators to capture the state of a file system at a specific moment. This functionality is crucial for storage management, as it provides an efficient way to perform backups and restore data without interrupting system operation. Snapshots are lightweight and quick to create, as they only store changes made after the snapshot was created, rather than duplicating the entire volume. This makes them ideal for environments where availability and service continuity are essential. Additionally, LVM snapshots are highly integrable with other data management tools, allowing administrators to perform maintenance and data recovery tasks more effectively. The use of LVM snapshots has become a common practice across various operating systems to ensure data integrity and facilitate disaster recovery, highlighting their importance in modern storage system administration.
