I did say I keep one in my fire safe, which to be fair I haven't tested to destruction, but it is British Standard certified.
I would never use a cloud company since as far as I am concerned I wouldn't trust one with my dead grandfathers toupee.
They don't care about security at all. Everything is a question of money. How little do they have to spend? How much can they charge? How big would the bribe have to be?
At least I am in control of my own security arrangements.

Of course I have a fireproof safe for the backups I keep at home* - you surprise me by asking


*Recently moved from an area where fires are not unknown and kept up the habit.

Couple lack of space with unreliable USB ports. Of course, then, a good answer would be, throu the computer into the paper basket. But I can't. Only choice left is the SD port. But I am even that short of money. All I bought is a 16GB SD.

Only speaking for myself here, but with my home burnt to ash, possessions gone, possibly needing hospitalisation - quite possibly lives lost - as a theoretical survivor, I would probably not be so worried about whatever files I thought were important.

If I did have important files - for example if I was working on a project which formed part of my livelihood - such as a book - I would not trust that to cloud hosting regardless. The company could go bust, could lose all your data, they could suffer a security breach, etc. There is also no real guarantee that my work is safe and secure. I would probably invest in a proven backup solution and/or pay up for dedicated hosting if it were that important.

In view of all this cloud hosting/backups still seems like a gimmick for now. If you have a smartphone and limited storage and want to access files everywhere, then it's most likely a convenience.

In fact your work has been disclosed to a third-party which will, given the present state of (non-)law on the subject, probably take for granted that you have ("in fine print somewhere") authorized them to analyze everything you've put there and sell it.

It has not escaped my notice that Apple recently sold an undisclosed amount of personal data to the Chinese ... nor that there seemed to be no objection to this, only a discussion of the price paid. "What Fools These Mortals Be!"
