It technically still exists in the game properties -> installed files tab, but it doesn’t really work. The backup files you get require you to be online to meaningfully restore and will trigger a patch to the latest game version.
Practically speaking it’s better to just make a copy of the game install directory manually, gives you a better chance of things working (even though most games require some kind of external tooling for that).
What the hell happened to Steam’s built in offline backup system, anyway? It used to have that when it was brand new.

It’s still there. But I never tried it and it probably won’t work with DRMed games.
