I want to experiment a bit with plugins, theme, etc. locally, to avoid the risk of breaking the real forum. But setting up everything to similar state as the real forum is difficult, so would be great to just restore the backup to the local instance.
But how should I do that to avoid the risks like sending emails to the real users from the local instance? Also maybe there are some other pitfalls that I am not aware of?
Is there any way to anonymize all user data in the backup (remove emails at least)? Or restore everything except the user data?
