<big>Welcome to CRIU, a project to implement checkpoint/restore functionality for Linux in userspace.
<big>Welcome to CRIU, a project to implement checkpoint/restore functionality for Linux.
Checkpoint/Restore In Userspace, or CRIU (pronounced kree-oo, IPA: /krɪʊ/, Russian: криу), is a software tool for Linux operating system. 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.
Checkpoint/Restore In Userspace, or CRIU (pronounced kree-oo, IPA: /krɪʊ/, Russian: криу), is a software tool for the Linux operating system. Using this tool, you can freeze a running application (or part of it) and checkpoint it as a collection of files on disk. You can then use the files to restore the application and run it exactly as it was during the time of the freeze. With this feature, application live migration, snapshots, remote debugging, and [[usage scenarios|many other things]] are possible.
CRIU started as a project of Virtuozzo, and grew with tremendous help from the [[community]]. It is currently used by (integrated into) OpenVZ, [[LXC]]/LXD, [[Docker]], Podman, and [[Integration|other software]], and [[packages|packaged for many Linux distributions]].
