I wrote my little consistency checker (https://github.com/jwr/ccheck https://github.com/jwr/ccheck) specifically for checking my image archives against corruption. I am appalled that in this day and age we still (mostly) use tools and filesystems that have no way of knowing if data has been corrupted. Before I wrote the tool, I searched online and couldn't find anything that would be small, simple, easily maintained, and would last for at least 10 years. I now use it with all my archives, which means I know if a given replica is correct.
