Systems and methods performing a database backup process are presented for reducing database load time. In some embodiments, a computer-implemented method may include marking a checkpoint in a log of the database; generating a backup of the database for data up to the checkpoint; recording first changes in the database while generating the backup of the database; adding to the backup of the database an additional backup of the recording of the first changes; recording second changes in the database while adding the additional backup; determining if a number of second changes satisfies a criterion; and if the number of second changes satisfies the criterion, then adding to the backup of the database a backup of the recorded second changes. Recording these changes can enable a database dump process to contain more recent page images, so that the amount of recovery at load time is reduced. |
