Gareth's stuff above is a bit tinfoil hat to me, but my scenario seems
to me to be a real (if low probability) threat. If you keep an off-site
backup that you don't declare to the police, presumably you are
committing an offence.

No, I don't think so. You're not generally obliged to answer police
questions after arrest, and there is of course no law requiring
disclosure of all backups *before* arrest.
