Abstract: This document describes methods and systems by which a data storage service migrates a volume of stored data from an unencrypted format to an encrypted format while still permitting user access to the data. The encryption process uses migration markers to identify records that have undergone the encryption process. When migration is complete, the service removes the migration markers and retains the encrypted data in a data storage facility.

Abstract translation: 本文档描述了数据存储服务将一系列存储数据从未加密格式迁移到加密格式的方法和系统，同时仍允许用户访问数据。 加密过程使用迁移标记来识别经过加密过程的记录。 迁移完成后，服务将删除迁移标记，并将加密数据保留在数据存储设备中。
