Abstract
A method and associated systems for synchronizing a disaster-recovery system of a database. A processor identifies transactions that affect data blocks of a database and records each change in a vector form. For each block, the processor determines a more efficient way to communicate changes made to the block by a subset of the identified transactions. If fewer resources are needed to communicate an updated image of the entire changed block than would be needed to instead communicate a related set of change vectors that identify changes made to the block by the subset of transactions, then the processor communicates the updated image to the disaster-recovery system. Otherwise, the processor instead communicates the related change vectors to the disaster-recovery system. The processor repeats these determinations and communications for each block of the database that was changed by an identified transaction.
