Abstract: Backup and restore of client-managed tables and system-managed tables in a same database may be performed. A request to restore a database with both a client-managed table and system-managed table may be received. The request may specify a point in time to restore the database. A metadata volume for the database that describes both the client-managed table and the system-managed table may be restored and used to identify the volumes for both the client-managed table and shards of the system-managed table. Redo logs for each of the volumes may be used according to timestamps that are synchronized according to a time synchronization service to generate restored versions of the volumes for the client-managed table and the shards of the system-managed table from backup copies, which can then be made available for accessing the database.
