FreeBSD and Caddy play very well together for static websites/reverse proxies but we often need to serve dynamic websites. Adding PHP is quite easy.
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.
If you are using Proxmox, ZFS is one of the best local storage options. You can easily backup your lxc containers using Borg.
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.
