The configuration and cluster state are shared accros the cluster nodes 
and physically stored in an XML file called a CIB (Cluster Information 
Base).
At a given time, the CIB stores the exact state of the cluster (with 
scores, roles, & such)

Assuming you just want to save your starting configuration and not the 
state of the cluster or anything complex, saving the output of "pcs 
config" is alright, and can be easily restored. But you could also 
create "shadow cibs" and restart from them (~ save points).

In any case, I'd say, do not touch the XML files.
