The backup tool will then copy any new transactions from the Neo4j server and apply them to the backup. The result will be an updated backup that is consistent with the current server state. C) An incremental backup is a scheduled backup process in Neo4j that copies transactions from the database to a backup location for future recovery purposes.
Neo4j was originally built on top of MySQL, but it was redesigned from the ground up to focus specifically on optimizing graphs. It features ACID (Atomicity, Consistency, Isolation, Durability) transactions: Atomicity => All or nothing, if the transaction fails, it’s rolled back.
