In a previous place I worked, we were programmatically using Box to store files. One day we were presented with a case study in Murphy's Law: a script went awry and deleted everything (10s of thousands of files). There was no clear way to recover these files, they were gone from what we could see. It was a disaster. We got a Box support person on the phone and described what had happened. There was a pause, some mouse clicking and then: "Ok, those files will be back in your account in an hour."

It was 100% our fault. But soft deletes saved us that day. If you're in a situation where you or your customers could benefit from the same, it's wise to not only embrace them but also make sure they work.
