''Main article: [[Memory images deduplication]].''
When iterative memory dumping feature (<code>criu pre-dump</code>) is used, memory is sent to page server a few times. The page server can automatically deduplicate pages, by punching holes in parent images where the child image is replacing an existing page. This functionality is turned on by <code>--auto-dedup</code> option of <code>criu page-server</code> command.
