* make automatic snapshots that you can recover data from as necessary, and have them be created every time the system updates (I've needed to use this once)
* have those automatic snapshots be auto synced to my NAS, creating a backup (also used this once when my hardware failed)
Define this.
But the simple, practical answer is no.
Quite frequently. It's not that uncommon at all. Bad disk cables, defective disks, etc it's not all that rare. The filesystem is in a place to either detect and/or correct these problems. Only some do.

I'm glad you've been lucky but silent file corruption is not an "irrelevant" problem as data densities increase.
Filesystems with data checksums include btrfs, ZFS, ReFS, NILFS. But very commonly used filesystems, xfs, ext4, NTFS, APFS, exFAT do not have this feature (some of them do have metadata support).

Unnecessary e-peening aside - Why do you think this is the case? What specifically about modern tech makes it irrelevant?
