Backup is not a tool. Backup is not a software you can buy. Backup is a strategy you need to study and implement to be able to solve your specific problems.
Many Linux users are asking how we’re migrating to FreeBSD, how jails can replace lxc or (in part) Docker, and how we’re monitoring and performing backups/restores.
Sometimes you want (or need) to assign a public OVH failover IP address to a FreeBSD jail but there’s not much documentation on how to do it inside a jail.
docker-compose allows you to define a set of containers in a single file. They will be in their “namespace” and can be linked and tied together.
What I’ll be describing now is another kind of setup, based on two containers, and it will help you to understand some of the features of Docker.
