Corrupt database file recovery apparatus uses change accumulation manager to read file in parallel with reading and recovery of secure copy

摘要

The apparatus includes a memory for storing executable modules, the modules comprising a recovering utility program having a secure copy recovery utility program for reading and recovering a secure copy of the database file. A change accumulation manager reads an accumulation file for changes in parallel with the reading and recovery of the secure copy, to derive detailed data sets. An image copier-recovery utility program uses the detailed data sets during the reading and recovery of the secure copy, to produce a recovered database file. Independent claims are included for a method of recovering a corrupt database, and for a computer readable medium storing instructions for performing the method.
