Docker images work great for this. In essence the master is just an image which you configure with all your jobs. Logging of course should not be stored on the docker image but piped to AWS S3 or some datastore.

Each job you run launches a new docker slave to handle that task. Offers HA with lots of room for horizontal scaling.

If docker/containers is not your thing, configuration management is the way to go (chef, puppet, ansible). Take your pick and use these tools to build out your consistent Jenkins master and restore from latest backup.
