Stress-testing my new cloud backup—how do I simulate a failure?

Hi everyone,

I recently set up a complex automated backup system for my small business, and I want to make sure the error-reporting feature actually works.

To do this properly, I need to make corrupt file samples that look like real database entries but are actually unreadable by the system.

My neighbor, who is a sysadmin, said this is the only way to be 100% sure the software won't just skip over bad data without sending me an alert.

I’m looking for a simple script that can help me safely make corrupt file.

Thanks in advance.
