Not a silly question.
Some background: We have to archive documents for various lengths of time. For a murder case, it's basically forever. When searching for a file from 2007, the file wasn't valid. Not a problem in this case in that they still had the hard copy of the file so they re-scanned it. I wasn't involved with the research of this file, but let's just imagine that the file existed but it was filled with garbage characters. (Worst case scenario.)
The way our offsite long-term backup system works, is that they will keep versions of a file that have changed in the last 30 days. After that, they start removing older files until the most current file is 30 days old and they will keep that forever. BUT, what if that current file is corrupted, and the older files were valid? It'd be better to know earlier than later.
Why wouldn't a file be valid? * Zero bytes long * Mis constructed header * Garbage filled file * Truncated file * Other file format saved with wrong extension ... more
Thanks everyone for their feedback!

Might be a silly question but if you found a file which wasn't valid, what you going to do?
