A snapshot is a point-in-time copy of a file system or a volume that captures the state and data of the fileshare at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the fileshare after the snapshot was taken. A snapshot can be used to restore the fileshare to its previous state in case of data loss or corruption.
