= Features/Checkpoint Restore = https://fedoraproject.org/wiki/Features/Checkpoint_Restore Feature owner(s): Adrian Reber <adrian@xxxxxxxx> Add support to checkpoint and restore processes. Checkpointing processes can be used for fault tolerance and/or load balancing. Checkpointing a process in regular intervals can help to restart a process if it might crash to resume/restart/restore the calculation without too much data lost. Providing this ability transparent at the OS level removes the need to implement this functionality for all processes manually. Checkpointing and restoring a process to another system can be used to migrate a process, process tree or container to another system to distribute the load during the runtime and also for maintenance without service interruption like it is possible with virtual machines. == Detailed description == Checkpointing/restore, as mentioned above, can be used for fault tolerance and load distribution. Fedora can offer checkpoint/restore by using CRIU (Checkpoint/Restore In Userspace). CRIU has been developed with the goal to be accepted by upstream and most patches necessary have already been accepted (as of 2012-10-24) in the kernel. The current release (0.3) of the userspace tools (crtools) offers the ability to checkpoint/restore containers and thus offering the ability to migrate containers. To offer the checkpoint/restore functionality the package crtools has been imported into Fedora and changes are still necessary to the kernel RPM. _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
