How to quickly get a snapshot of the Heimdal DB file

I am looking for a quick way to get a snapshot of the Kerberos database 
file.

The most obvious way to do this would be to shutdown the kerberos 
service, copy the file, and restart the service. This could be done on 
one of the replicas, perhaps one that does not get actual authentication 
requests.

Is there a faster way? For example, some database systems (e.g., MS SQL) 
have the ability to go into and out of a "quiescent" state faster than a 
full service stop/start to facilitate this sort of thing. Does Heimdal 
have something like this? Or is the full service restart the only/best 
option?

Thanks, Adam Lewenberg
