An resource is called "external", if it can't be dumped and restored without some help from the caller. Usually this mean that a part of it state is out of a dumped container.

The general approach is to enumerate all such resources on dump and set one of restoring strategies for each of them on restore. An approach how to restore an resource may be different for different types of resources.
+
== Dumping ==
 +
 
 +
Typically external resources are just told to be such on dump. The respective option looks like <code>--external TYPE[ID]{:VAL}</code> option, where TYPE is resource type, ID is resource ID and :VAL is optional argument.
 +
 
 +
== Restore ==
 +
 
 +
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.
