A key made by mistake on a server that is being restored left no way back: key:import and the
passphrase route refused because a key existed, and nothing removed it. As long as the key never
protected anything (no location created or adopted with it, no location or run in the database),
occ backup:key:import --replace-unused-key and occ backup:target:add --replace-unused-key replace
it, after the new key was opened. A key that was used is never replaced, also after its location
was removed. The refusal names the option, and all administrators are notified of a replacement.
