Line 38:
Line 38: − After creation of such stack of images some data would get duplication in dumps. If you don't want to keep duplicates there's an ability to punch duplicate data from non-top images. There are two options for this.+ − − === Deduplication action === − The <code>criu dedup</code> command opens the image directory and punch holes in the ''parent'' images where ''child'' images would replace them. − − === Automatic deduplication while dumping === − The <code>--auto-dedup</code> option would cause every write to images with process' pages to go an punch holes in respective parent images. − − This option applies to both <code>dump</code> and <code>page-server</code> actions and thus is extremely useful in [[disk-less migration]] scenario.
