Looking for some help with using the HFB CP.

Started my server a few days ago had a few general questions.
When expecting an update, what files do i need to backup to ensure there is no wipe on my server.
Also i run Oxide Mods, anyone using HFB have them fully up and running, after the last update i am still not able to access the plugins after re installing them.
may have a few more questions, anyone here able to help?
