Warren,
A listed contact for the account in question would have to write to the Service desk with specifics.
Service@FutureQuest.net
Note that we do back up both web files and MySQL databases nightly however they are meant for restoration in the event of a catastrophic server issue and not for individual site restoration purposes.

We usually can restore databases from the most recent backup, usually about 2 - 3 AM ET the night before however there is a service fee.
