Yes, I would recommend having your files backed up, or at the very least, creating frequent library backups under Settings->Backup and Restore->Backup Library. You can also use Sync Library->Sync to a cloud folder, and keep your library synchronized to the cloud in case you ever need to restore something (you can actually reverse changes this way by performing a one way merge from the cloud folder back to the device and changing the merge behavior to "prompt user for decision" so you can review each change). 

I will absolutely accept your offer to help, but I won't hold you to it. I have quite a lot I need to finish before I create the new manual. The reason I'm waiting is because some of the changes I'm making are pretty large. It doesn't make a lot of sense in my mind to finish the manual and then have significant changes to the application that requires big parts of the manual to be rewritten.

Thanks,
Mike
