While I agree snapper (what CachyOS uses) I very useful, it is important to draw a distinction between snapshots (snapper) and a proper backup tool (borg or restic). Snapshots are usually stored on the same drive, so in the event of a drive failure/corruption you are still very fucked. Proper backup programs also have other important features, like the ability to select remote locations, setup encryption, etc. DO NOT rely on snapper to (always) save your ass.
That being said, I fucking love snapper and it was the main feature I was missing from openSUSE.
While the distinction can be important, the snapshots from right before the update are exactly what you want in this case over some actual but always somewhat outdated real backup

Snapper can save you from OS destruction, not disk destruction.
