# Partial sync sample atom ('stps')

An atom that lists the partial sync samples.

## Overview

Overview Since such samples are not full sync samples, don’t list them in the sync sample atom. The type of the partial sync sample atom is ‘stps’. The layout of the partial sync sample atom is as follows.  |   |   |   |   |   |   |
