Summary: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 timefiow stored in a respective container. A user can send a request to rewind a VDB. The request identifies timefiow of the VDB and a state of the VDB associated with a timefiow. The database storage system modifies the virtual database to refer to database blocks associated with a snapshot of the VDB associated with the identified timefiow. The database storage system maintains a new timefiow 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.
