The problem with backups is that with a site that operates like this one, with an average of thousands of users online at any given moment, with tens of thousands of posts being made, losing a single (or two, or even three) forum(s) to error versus losing thousands of posts in hundreds of forums due to backup recovery means taking the lesser of two evils - and that would be accepting the loss of a single (well, two, really) forums and moving on.
A backup would only have worked if 1) it was continuous and 2) it was restored immediately upon discovery of the error, minimizing the loss of posts in non-affected forums. And continuous backups are expensive. If the backups were not continuous, meaning there are time increments when the backups are performed, then every post made after said backup would be lost in the interim backup reload.
If this had been an active forum with help, info, troubleshooting, etc., as opposed to a forum created for a device that is not in anyone's hands yet, it might have been different.
And I, too, have managed and moderated numerous forums in the past. I'm sure that Phases is extremely thankful that this happened with these forums as opposed to something insanely large, like, for instance, the Motorola DROID forums....
