Uh.I didn't find this action in the control panel so I am afraid they do not provide it.And yes,seems most sites will not let you take backups .Here instant messangers are more popular than forums.Forums are decaying now.

Forums indeed are slowly losing their former glory. I think Facebook Group is now more popular as an alternative. Doesn't all those functionalities of a forum and easier for everyone to use. Inability to taking a backup is the biggest drawback in those free forum sites. YOu are stuck there forever. If they decide to close the server your forum is doomed.
