OPTIONS

--image-path path

Set path for saving criu image files. The default is ./checkpoint .

--work-path path

Set path for saving criu work files and logs. The default is to reuse the image files directory.

--parent-path path

Set path for previous criu image files, in pre-dump.

--leave-running

Leave the process running after checkpointing.

--tcp-established

Allow checkpoint/restore of established TCP connections. See criu --tcp-establised option ⟨ https://criu.org/CLI/opt/--tcp-established⟩ .

--ext-unix-sk
