[jira] [Commented] (IGNITE-6781) Should we prohibit change of backups count if persistence is enabled?

    [ https://issues.apache.org/jira/browse/IGNITE-6781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16223617#comment-16223617 ] 

Dmitriy Setrakyan commented on IGNITE-6781:
-------------------------------------------

I do not understand. What currently happens if the persistence is enabled and backup count goes from 1 to 2? Does Ignite create an additional copy or does it ignore the change?

> For now Ignite allows to change number of backups in CacheConfiguration between grid restarts with persistence enabled. I mean no error will be thrown.
> If user get cache configuration object after restart it will see new configuration,
> but user see restored configuration from persistence in Visor after grid restart.
