Abstract: Various embodiments are generally directed an apparatus and method for performing a discovery operation to determine a system layout for a database and one or more files for a dataset stored in the database and performing a backup operation on the dataset to cause storage of a backup copy of each of the one or more files and collect metadata associated with the backup copy of each of the one or more files, the metadata to enable restoration of the one or more files.

Abstract: Example embodiments provide various techniques for updating an old data structure configured to store metadata associated with database systems. In this method, a temporary data structure is created. Additionally, a new data structure representing an update of the old data structure is created. The metadata from the old data structure are copied to the temporary data structure, and the temporary data structure is transformed to match the new data structure. The metadata from the transformed temporary data structure are copied to the new data structure. The transformation of the temporary data structure instead of the old data structure may enable an application that is not being updated to be operational and to access the old data structure during the update. After the metadata is copied to the new data structure, a new version of the application is then able to access the new data structure.

Abstract translation: 示例实施例提供了用于更新被配置为存储与数据库系统相关联的元数据的旧数据结构的各种技术。 在该方法中，创建临时数据结构。 另外，创建表示旧数据结构更新的新数据结构。 来自旧数据结构的元数据被复制到临时数据结构，并且临时数据结构被转换以匹配新的数据结构。 来自变换的临时数据结构的元数据被复制到新的数据结构。 临时数据结构而不是旧数据结构的转换可以使得未被更新的应用可以运行，并且可以在更新期间访问旧的数据结构。 元数据被复制到新的数据结构之后，新版本的应用程序就可以访问新的数据结构。
