Closed HenrikBengtsson closed 1 year ago

From https://github.com/checkpoint-restore/criu:

CRIU -- A project to implement checkpoint/restore functionality for Linux

CRIU (stands for Checkpoint and Restore in Userspace) is a utility to checkpoint/restore Linux tasks.

Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space. There are some more projects doing C/R for Linux, and so far CRIU appears to be the most feature-rich and up-to-date with the kernel.

Requires sudo to use, so not a tool for a non-privileged user.
