Everything that runs in the container is in a configuration management
system, so any container can be redeployed from scratch in just a couple
of minutes without needing the actual rootfs.

On top of that, all the containers are backed up centrally using data
deduplication, so if I really need it, I can extract a .tar.gz of the
rootfs of any container in minutes and then just dump that on another
machine.

Though technically all the critical services are already redundant, so
in case of a host failure, all I'd see is an increase of load on the
other servers while I fix the host and get the rest back online.
