You can create a nested ZFS file system and set the number of copies of the various blocks to be two or more. This will take more space, but there'll be multiple copies of the same block of data.
Ideally, though, please add an additional disk and set it up as a mirror.
ZFS can detect the silent data corruption during data access or during a zpool scrub (which can be run on a live production server). If there happen to be multiple copies, then ZFS can use one of the working copies to repair the corrupted copy.
