Snapshots capture block-level changes of a volume’s state at any point in time. StarWind Snapshots can be created manually using a corresponding option in the snapshot manager. Snapshots provide a fast and efficient method to backup & restore data right on the SAN with minimal impact on the application performance. Since snapshots only capture block-level changes, they occupy far less space than a full copy. Further, replicating data from a snapshot means you don’t negatively impact live production LUNs, eliminating performance degradation for applications and servers, as all the work is done on the SAN.
