In an approach for optimizing resources in a disaster recovery cleanup process, processors are configured for receiving transaction entries represented by transaction identifiers at a source database in communication with target databases via Synchronous-to-Asynchronous Traffic Converters (SATCs). Further, the processors are configured for transmitting a transaction payload from the SATCs to the target databases; identifying completed tracking entries corresponding to tracking entries having a complete status for the SATCs; deleting remaining transaction entries ranging from a transaction entry associated with a highest processed transaction identifier to a transaction entry associated with a lowest processed transaction identifier; providing a list of the remaining transaction entries that were deleted to predecessors of the SATCs; removing the remaining transaction entries from the SATCs if the transaction entries were delivered to all target databases; and detecting a topology change corresponding to one or more additional SATCs integrated with the one or more SATCs.
