journalling ⇝

journal

<operating system>

An on-going record of transactions, such as database updates, file system writes, procedure calls or message transmissions. A journal differs from a simple log in that the contents of the journal can be used to reconstruct the state of the system after a failure by re-applying the transactions in the journal to a snapshot of the system previous state.
