      For cost effective, a box at home is the best, obviously.

        If you don't want VMs, containers are lighter and faster. So pretty much any system where you can run LXC will do nicely.

          Yup. Exactly what I do on Vultr, and I have a VM at home for LXC. XO runs in LXC and when a new version comes out, Ansible clones it and updates it for me but leaves the old container. I don't have to do any work at all. Then if a bug happens like the recent backup to NFS bug, I just use the old container.

              LXD is an LXC interface.

                With containers I might not need nearly as much RAM 🙂

                  Ubuntu is working on live migration with LXD. That will be awesome.

                      Just tar the container folder. You can also do file level backups of the containers. LXC by default stores everything in /var/lib/lxc/ so if you want to restore a file to container1 you could just cp it back to /var/lib/lxc/container1/root/pathtofolder/

                          Can I run different Distros in containers or just the same as the host?

                            Which file level restore or using tar?

                              You can run different distros. But I think you need to match systemd and init between host and container though.

                                @johnhooks tar. I assume rsync would work too?

                                  I think you have to stop the container to do that. Ya rsync works also.

                                      @johnhooks should be super easy to write a script to stop containers, tar them and start them again.

                                        I know Ubuntu 15.10 is systemd, CentOS 7 is also systemd. So if you run a CentOS 7 host you can run Ubuntu 15.10 containers (what I'm doing for my XO container).

                                          ya. I use Ansible, but you can script it also.

                                            I will be using Ubuntu as the host. CentOS7 as the guest 🙂
