Back up the local data.mdb file

We need to back up the /objectbox/objectbox/data.mdb file, and we need to ensure that the database is complete and that the current data is not being written. We don't currently find an API that can be used.

Our current solution is to start a transaction and copy the database file in the transaction to avoid other writes during the copying process. Will it cause other problems?

sBoxStore.runInTx(new Runnable() {
        @Override
        public void run() {                
               use FileUtils copy data.mdb to backup_data.mdb
        }
    });

Start by reviewing the data.mdb backup scenario and the Store.runInTx approach described in the issue, then identify the available database and transaction APIs. Determine the supported way to produce a complete backup without concurrent writes; done means the API or its limitation and consistency guarantees are clearly established.
