Incremental snapshot is a lightweight alternative to full snapshot. It bases on the non-blocking Consistent Cut algorithm and provides a collection of WAL segments that hold logical changes since previous snapshot (full or incremental).

Incremental snapshot should contain:
 * compacted WAL segments
 * meta file with Consistent Cut to restore on

Incremental snapshot is stored within full snapshot directory.
