- Check if the current kernel has support for the necessary CRIU features:
|
||
|
|
|
||
|
|
`sudo criu check`
|
||
|
|
|
||
|
|
- Checkpoint a process with a specific ID, saving the state to a specific directory:
|
||
|
|
|
||
|
|
`sudo criu dump {{[-t|--tree]}} {{process_id}} {{[-D|--images-dir]}} {{path/to/directory}}`
|
||
|
|
|
||
|
|
- Restore a process from previously saved image files:
|
||
|
|
|
||
|
|
`sudo criu restore {{[-D|--images-dir]}} {{path/to/directory}}`
|
||
|
|
|
||
|
|
- Dump a process and allow it to continue running instead of terminating it:
|
||
|
|
|
||
|
|
`sudo criu dump {{[-t|--tree]}} {{process_id}} {{[-D|--images-dir]}} {{path/to/directory}} {{[-R|--leave-running]}}`
