摘要： An automatic database backup and restoration system comprises an interface component that receives statements relating to backing up at least a portion of a first database, the original database resident upon a consumer computing device. A backup component associated with the interface component automatically copies at least the portion of the first database and writes the copied portion to a backup database, the backup database is a full backup of the first database. The consumer computing device can be, for example, one of a laptop computer, a desktop computer, a personal digital assistant, and a cellular phone.

摘要： The creation of multiple recoverable units within a database allows a database partition to be reconstructed during maintenance and disaster recovery operations. A method of creating a recovery unit includes partitioning a database into at least two recovery units. A primary catalog of metadata relating to the logical elements of a database such as tables, indexes, and file groups is created. A secondary catalog of metadata relating to the physical elements of a database such as pages, files, B-Trees, and log streams is created for each recovery unit. The primary and secondary metadata catalogs are linked such that only one log stream is associated with any one recovery unit. A single recovery unit may then be exercised to perform recovery or maintenance operations while the remaining recovery units of the database remain online.
摘要翻译：在数据库中创建多个可恢复单元允许在维护和灾难恢复操作期间重建数据库分区。创建恢复单元的方法包括将数据库划分成至少两个恢复单元。创建与数据库的逻辑元素（如表，索引和文件组）相关的元数据的主目录。为每个恢复单元创建与数据库的物理元素（如页面，文件，B树和日志流）相关的元数据的二次目录。主要和次要元数据目录被链接，使得只有一个日志流与任何一个恢复单元相关联。然后可以执行单个恢复单元执行恢复或维护操作，而数据库的其余恢复单元保持在线。
