To be clear I can't agree more! I got a little lost while writing. But indeed my point was double check! Because in my case everything looked fine at first sight. This is even why I don't use the same process for my two backup (daily/monthly). Because to be fair you can't constantly check that your daily/hourly backup isn't corrupted, you rely on its build-in safeguard and occasionally you check it. But by using two different methods for daily vs monthly(offsite) backup, you significantly reduce the odds that the two different methods failed at the same time while you need them. (Also a monthly full clone is way easy to check than a Time Machine Disk)
