And, I don't think I am doing anything particularly special, either. I also compact and backup regularly. Pre-patch, I did have to restore from my backup once.
I work almost exclusively from my ancestry member tree, using FTM for its reporting capability. I will occasionally make a "fix" in FTM, when it is something I can't do from AMT - like finding unlinked media, left over when I have deleted someone without first deleting or unlinking the attached media to that profile.
