Hello,

In the DB is stored some data, which must be hide from another's eyes
in minimum time.

I mean situation like check of tax police or something like that. If
this police came any user can press BIG RED BUTTON and all unlegal data is
"lost" :) but it must be restored when check ended...

What is the fastest decision of following problems:
- copy to flash drive data from "unlegal" columns
- delete permanently from DB all data and information about this columns

Thanks.
