You absolutely should NOT automate this. If you do, you then need to manually check that automation with the same frequency- so you haven’t gained anything!
I do have this automated, but the checksum output is posted to a kind of watchdog service. Every day I get an email that says everything is as expected, or not.
I need to google every time to find a good process for hashing files and comparing across disks? Not only that, but remember to do it frequently enough?
