Too late now, but it's a good idea to keep your own backups of all your FB data. There is a well-hidden option under the settings to make and download a zip file with all your posts, comments, photos, everything. Worst case this can be used to rebuild your community elsewhere.

I am sure it would be nice to have but a backup of a community isn't worth much if you can't re-establish it with a "restore" function.

How would you rebuild a community - start a new Page on Facebook and re-invite all you previous followers?

Probably difficult as FB used to allow a lot more leeway on how FB groups and their posts were shared. The road to xx,xxx group members is a lot harder than it once was.
