Abstract
In order to correlate or synchronize the database of a source primary host with the backup database of a remote secondary host, the present method operates to speed up the transfer of audit blocks from primary host to secondary host when an out-of-sync signal indicates the secondary host audit blocks are not on a par with the primary host audit blocks. A Catchup process utilizes multiple buffers of audit blocks at the primary host which can then be asynchronously transferred, by a sequence of Catchup tasks, on a parallel concurrent operation, over to physical files of said secondary host.
