This is a quick setup for Tarsnap on Parallels Cloud Server 6. See my other post for general Tarsnap on CentOS setup.
Hardware Node
Here we're concerned with backing up the hardware node itself, not the container and virtual machine data in cloud storage (pstorage).
Exclusions
PCS uses /pstorage/ for all it's MDS and CS device mount points, as well as the client pstorage mount; we want to backup all the directories themselves, but nothing under those.
Container mount points are under /vz/root/, which we'll exclude.
Backups get put in /vz/backups/, which we'll also exclude here.
Templates are kept under /vz/template, which you may not want to backup. Certainly if the same templates are maintained across all your hardware nodes, you don't need to back that up everywhere.

That should be enough to backup the hardware node itself, though a clean install may be nearly as fast to setup. If you like, kick off a daily backup now:
/usr/local/bin/tarsnap-archive.sh daily
Now to backup the containers and virtual machines.
Virtual Environments
More to come...
