Backup Questions

Hey guys, I am very new to Kodi and I have been trying to make an exact copy of one installation of Kodi and no backup add-ons seem to work. Any help would be extremely appreciated as I have tried XBMC backup and USB-SD wizard,the latter of which just kept crashing. I hope someone has an idea as I really love Kodi but this would be extremely helpful. Thank you hope to hear back soon ^^
