This is still possible to extract the DB content using a search request,
but this is not even close to what you are looking for...

That would deserve a JIRA, this is a feature we would lov to have in a
future version, but as the backend files are growing on the fly, the
best possibility would be to have a replica which is updated on the fly,
and periodically stoppped while being backed up.

Note that even if the server crashes, the data wont be lost, as we use a
transaction journal which recover the last modifications and reinject
them in the backend at startup.
