Hi, @Paul. Mesos support recovery well when your server crash. For Mesos Master, I suggest to set up multiple masters with zookeeper, so that the Mesos cluster would not be affected after some of Mesos Master down. For Mesos Agent, it would recover tasks information after restart.
About backup, I am not clear about your idea here. Do you mean backup to snapshots in every interval and recover to any timepoint? If you mean this, Mesos doesn't support this yet.
