Full restore in Freepbx 15

Can anyone tell tell me what to backup in Freepbx 15 to get a COMPLETE backup. All settings including IP’s , trunks, IVR’s ,etc. I’ve included what I backup but it does not work when I try and restore it on a fresh install of version 15 with fully updated modules.( it trashes the system)

Select full backup and make sure voicemails and sound files are included. That is a full backup.

If you’re referring to templates, those were removed in version 15.

I thought you were using a <15 version because of the capture you posted. Select all the modules. Done.
