+</div>

+<p>The snapshot structure is similar to the layout of the

+media where Ignite Persistence keeps data, index, WAL, and other files. Since the snapshot can consume as much space as

+Ignite Persistence routines, it’s suggested to store the snapshot and persistence files on different media.</p>
