Not good enough, you can make 10000 backups of bitrotten data, if you don't have check-sums on your block (zfs) or files (restic) nothing can help you. That's the same integrity as to copy stuff on your thump-drive.

The same applies to those filesystems on Linux which don't check for bit-rottenness, which will be the majority of installs.

Your average grandma would use ext4 when using Linux. Android phones don't do that as well and I don't know about iOS, but apparently APFS only does metadata checksumming.
