Typically external resources are just told to be such on dump. The respective option looks like <code>--external ''TYPE''[''ID'']:''VAL''</code> option, where <code>''TYPE''</code> is resource type, <code>''ID''</code> is resource ID and <code>''VAL''</code> is optional argument.

Restoring external resources heavily depends on its type. Some resources can be restored by CRIU itself with the help of <code>--external</code> option, some cannot. See below for further details.
