Recommend best backup

Now ive got my nexus 7 lte running just as id like and all my apps in place, i decided it was time to backup. Could any one recommend the best route, program to accomplish this. ideally id like to basically have an image of my entire device to restore. Any advice as always greatly appreciated. Currently googling it to death, thought id ask here as i search. Many thanks.

Nandroid backup through TWRP (recovery) is a full image. Titanium backup for individual apps and their data.
