Ignite backups=1 works incorrectly - ignite

Question

I am using pure in-memory ignite on k8s. There are 3 instances with backups=1 as the config below. I tried to restart one instance to see if it will be re-fill after restarting but the size of all other instances was reduced instead of re-filling the restarted one.
Size of Ignite cache
my config
<bean class="org.apache.ignite.configuration.CacheConfiguration">

<property name="name" value="dmp_user_mask"/>
<property name="cacheMode" value="PARTITIONED"/>
<property name="partitionLossPolicy" value="IGNORE"/>
<property name="backups" value="1"/>
<property name="onheapCacheEnabled" value="true"/>

<property name="batchSize" value="1024"/>
<property name="maxSize" value="#{100L * 1024 * 1024}"/>
<property name="comp" ref="sorted_value_eviction"/>
</bean>

<constructor-arg value="10"/>
</bean>
</constructor-arg>
</bean>
</property>
<property name="statisticsEnabled" value="true"/>

Is there anyone have an idea to fix it?
Thank you
