A Riddle

Wretchard asks:

Let's suppose I had an array of email stores that were going to be the subject of investigation. I know this because someone in the investigative agency tells me so.

In order to protect the organization(s) I first back up the array of email databases and put them on removable media. I can then screen the original databases for inappropriate entries and delete them as private secure in the knowledge that all past deals and correspondence can be referenced by very careful and surreptitious restores from the hidden archive.

I will have lost no data, just put them where it cannot be found. This archive, to have any relevance, must be close at hand and airgapped from the other computers. Could work right?

But suppose the person consulting the archive is observed by a third party, whose is ignorant of the arrangement and is probably ignorant period. Neverthless his sly nature leads him to suspect that data on the removable media is important owing to the secrecy with which it is consulted.

So he watches silently with his curiosity piqued.

At a moment of opportunity said ignorant person copies the contents of the removable media, still oblivious to its important. There it lies, unremarked, until one day it is discovered by a serious of fortuitous events by someone investigating an unrelated matter.

He has the Ring of Power in his possession but to him it is just a bauble.

What has roots as nobody sees,
Is taller than trees Up, up, up it goes,
And yet never grows?
What Bilbo? What?

AVI has some Lord of the Rings thoughts, too.
