Subject Re: Hot-backup strategy

From a RDBMS point of view, if the vendors tools claim consistency, then that what you will
get, only for the RDBMS.

You will need to do 
DB backup
Datastore (assuming file persistence) backup , since its append only and will be consistent
with the DB.
in that order.

You might also need so capture the local lucene index state, but that starts to get complicated.
I cant remember how it rebuilds from scratch (if it does)?
