a simple question about data storage

I use Zenfire data and Open&Cry data in Quotemanager.
Zenfire and OEC permit the data backfill even for Tick, but if my quotemanager requests data from Zenfire server or from OEC server, the data sent, will be stored in My Quotemanager History data, or they are only used as ondemand data for that single event ?
If I work offline, after backfill some days of data, can I plot my charts ?
Can I export a complete backfilled data serie from Quotemanager Zenfire symbols after a request of backfill ?

Thanks
