spring batch vs quartz jobs?

There is answer for this question in official FAQ

How does Spring Batch differ from Quartz?

Is there a place for them both in a solution? Spring Batch and Quartz have different goals. Spring Batch provides functionality for processing large volumes of data and Quartz provides functionality for scheduling tasks. So Quartz could complement Spring Batch, but are not excluding technologies. A common combination would be to use Quartz as a trigger for a Spring Batch job using a Cron expression and the Spring Core convenience SchedulerFactoryBean.

Quartz is a scheduling framework. Like "execute something every hour or every last friday of the month"

Spring Batch is a framework that defines that "something" that will be executed. You can define a job, that consists of steps. Usually a step is something that consists of item reader, optional item processor and item writer, but you can define a custom stem. You can also tell Spring batch to commit on every 10 items and a lot of other stuff.

You can use Quartz to start Spring Batch jobs.

So basically Spring Batch defines what should be done, Quartz defines when it should be done.
