I received a lot of downvotes but my comment was a bit ironical since in many forums (even in HN in the past) when someone talked about backups many people suggest the block chain.

I said: With the current and future block size it will take sometime to make it happen.

The absurdity of that suggestion it not absolved by the fact that someone else has said it before, or by the fact that you said it will take 'some time for it to happen'. It's completely not an option for the migration we're discussing.

It is not absurdity if it is irony and I clearly said that it can't be done now but may be in the future. I can't see the future, do you?

It's not practical, but it's a worthy goal for blockchain computing, or some descendant of it. So I am glad you brought it up.
