The <code>--auto-dedup</code> option can be used for <code>criu dump</code>, <code>criu pre-dump</code> and <code>criu page-server</code>. It causes every write to images with process' pages to punch holes in the respective parent images, which is extremely useful in [[disk-less migration]] scenario.

The <code>--auto-dedup</code> option can also be used for <code>criu restore</code>. This makes CRIU to punch holes in images as memory is being restored. This should be used if images are stored on tmpfs (i.e. in RAM, see [[disk-less migration]]), as this way RAM usage is not growing.
