Abstract: A data storage system protects data identified for deletion which has been created or modified between scheduled data backups. For instance, the system monitors data operations and when the data operation is a delete, the system determines whether the data identified for deletion has been protected by a backup operation. Data that has not been backed up, such as newly created data, is copied to temporary storage before deletion. When the data has been protected, the system determines whether the data has been modified after the backup operation. Data modified after the backup operation is copied to temporary storage before deletion.

Abstract translation: 数据存储系统保护已经在计划的数据备份之间创建或修改的被识别为删除的数据。 例如，系统监视数据操作，当数据操作是删除时，系统确定被识别为删除的数据是否已被备份操作保护。 尚未备份的数据（如新创建的数据）将在删除之前复制到临时存储。 当数据受到保护时，系统会在备份操作后确定数据是否被修改。 删除后将备份操作后修改的数据复制到临时存储。
