CRIU (Checkpoint/Restore In Userspace) is a Linux utility that freezes running applications and checkpoints their state to disk, then restores them from that point later. It is the core technology behind live migration in OpenVZ, LXC/LXD, Docker, and other container software.
Use cases
- checkpoint and restore a running linux process
- live migrate containers with zero downtime
- snapshot application state to disk and resume later
- save and restore tcp connections across restarts
- migrate docker or lxc containers between hosts
- create highly available services by checkpointing state
- dump process memory for debugging or forensics
When to choose
- you need to freeze and resume linux processes or containers without losing state
- you want live migration of containers between hosts
- you need process-level snapshots for fault tolerance or fast startup
When to avoid
- you are not on linux, as CRIU depends on linux kernel features
- your application uses kernel features that cannot be checkpointed
- you only need virtual machine migration rather than process-level checkpointing
