I think anyone doing production administration would be using some storage level snapshots. Also updates are rarely done in production. Typically new VMs are spun up, from prebuilt images that contain the new updates.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I would use BTRFS and Snapper over using Timeshift due to the lack of granularity it has. You should be able to back up any volume you want, not just the home directories like Timeshift does.
I use sanoid on my home server. I'd assume most large scale environments are using zfs or a proprietary solution.
