Interfacing with a virtual database system
User interactions with a database storage system allow creation of virtual databases based on point-in-time copies associated with a source database. Multiple point-in-time copies are obtained for each source database. A point-in-time copy retrieves data changed in the source database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system and mounting the files on a database server allowing the database server to access the files. User interactions allow the user to specify the source database, a point in time associated with the source database and a destination server to create the virtual database. User input can specify other attributes associated with the virtual database including the file paths, database parameters etc. The user can specify schedules of various actions, including making and retention of point-in-time copies.
