Scrub started/completed and no other messages

I recovered the file from backups - my daughter playing in a concert!
I remain concerned, here's why:
- Copying the errored file from Windows (NAS to desktop), the copy succeeded without error. Whilst the video file played, there was a small corruption part way through. It seems video files can be quite resilient to small corruptions.
- Alarming is that the NAS provides no obvious indication that there is a problem with the file.
- Only if you dig through system logs do you get a hint, thankfully (and by chance) I did that.
- I could have easily recycled my backup drives and overwritten the good file with a new backup containing the bad file.
I am running a "disk test" on the RN214, I have no indication when that will finish.
I am still wondering if this is a one off error, or if there is a bigger problem brewing. Any thoughts on how I progress?

Hard to say what happened here, or when it might have happened.
You could do a factory reset, but keep in mind that if there are other errored files they could be errored on your backup as well.
Another option would be to try to verify the backup (comparing each file in the NAS with the backup). You can create a script to do that, but there are also some free software tools that will also do it. I haven't used teracopy for a while, but I believe that has a verify feature - computing checksums on each file in the source and destination, and making sure they match.
