Abstract
Some embodiments provide methods and apparatuses for performing a near-instantaneous restore of a database. During operation, the system intercepts a database management system restore request to restore a database from a backup file to a data file, wherein the backup file comprises a first number (e.g., N) of data pages. Next, in response to intercepting the database management system restore request, the system sends information to the database management system indicating that the backup file comprises a second number (e.g., N) of data pages, wherein the second number of data pages is less than the first number of data pages (e.g., N<N). Once the database management system has copied the fewer number of data pages from the backup file to the data file, the database management system may indicate that the restore is complete, and continue processing database requests as if the database management system was back online.
