The Neo4j Manual v2.1.224.3. Online Backup from Java

In order to programmatically backup your data full or subsequently incremental from a JVM based program, you need to write Java code like

OnlineBackup backup = OnlineBackup.from( "127.0.0.1" );
backup.full( backupPath.getPath() );
assertTrue( "Should be consistent", backup.isConsistent() );
backup.incremental( backupPath.getPath() );
