Abstract: A database storage system allows users to modify the state of a virtual database. The database storage system provides a respective virtual database (VDB) at a respective destination, the respective VDB having a first timeflow stored in a respective container. A user can send a request to rewind a VDB. The request identifies timeflow of the VDB and a state of the VDB associated with a timeflow. The database storage system modifies the virtual database to refer to database blocks associated with a snapshot of the VDB associated with the identified timeflow. The database storage system maintains a new timeflow for the modified VDB. The database storage system also allows the virtual database to be refreshed to a state of a source database. The source database can be a database stored in an external system or a virtual database stored within the database storage system.

Abstract translation: 数据库存储系统允许用户修改虚拟数据库的状态。 数据库存储系统在相应目的地提供相应的虚拟数据库（VDB），相应的VDB具有存储在相应容器中的第一时间流。 用户可以发送请求以倒带VDB。 该请求标识VDB的时间流和与时间流相关联的VDB的状态。 数据库存储系统修改虚拟数据库以引用与与识别的时间流相关联的VDB的快照相关联的数据库块。 数据库存储系统为修改的VDB维护新的时间流。 数据库存储系统还允许将虚拟数据库刷新到源数据库的状态。 源数据库可以是存储在数据库存储系统中的外部系统或虚拟数据库中的数据库。
