Well, I am at a loss.

There is nothing amiss in the system that I can tell (I am the system developer), and if this was a recent system issue, other clubs would be reporting it, also. I see from your Member Access Log that your members have been pretty active on your website--do you share your admin password with anyone? Was this a long home page (over 60k)? ... There is a content length limit (@65k) which we do show a warning for. Any photos that were uploaded should still be on the server as those are stored as files, not in the db.
I tried looking in several web archives, including Google Cache, Bing Cache, and the Wayback Machine archive, and I did not see anything usable for recovery. Jane is sort of our de facto guru of data recovery--she never ceases to amaze me with her ability to recover lost information using web archives and the like. Hopefully, she will chime in and have something in her bag of recovery tricks to assist.
We do back up the entire db every 4 hours. However, while we can restore specific tables in their entirety from the backup, I do not believe we can restore specific clubs (parts of multiple tables) from it--Brian may have an approach for that. Thus, the db backup is more for catastrophic data losses and code issues that mangle a specific table. This is why we do recommend saving your web page content to a local file via the Web Page Tools. I also will be putting some additional data recovery measures in place in the future. (which obviously does not help us now)
Again, I am very sorry--I never want anyone to lose content which I realize frequently takes a good bit of time and effort to create. I just don't see any viable approaches to recover this information.
