Survivability after some tiers just becomes an issue - you can improve it by equipping some more defensive choices in cube or in open slots, like Aquila Cuirass or Ancient Parthan Defenders and so on - but later on in the game you will eventually be squishy, on any class, especially once you go above GR 100+.
I haven't played barb myself in a while, but if you play on PC you can link your profile by going to diablo3.com and logging in. I don't think such an option exists on console.
