Re: Making a copy/image of the backed up data

Is there a way of creating a copy or image file of the data, that'salready being backed up to tape?
We've already got Amanda running on our system with two tape devices
running well. We'd like to produce a (encrypted) copy of the backed up



Would this work?

  while dd bs=32k if=/dev/nst0 of=/dev/nst1
  do :
  done

or with encryption:

  while dd ibs=32k if=/dev/nst0 | encrypt | dd obs=32k of=/dev/nst1
  do :
  done

Whatever you use for encryption, the script could be changed of course.

Maybe there is some elegant solution using RAIT (never used it;
never done it).
