If I can read this properly, you suggest to make the copy of the image to
the second tape drive. But we need both tape drives for backup reasons.
The image should only be dumped to a file. But I think, there would be the
possibility to mount a image file as device and tell dd to copy the data
to that one :-) Problem could be the variable size of this image device.
But thnx a lot for your idea!
If you want the images from tape simply dumped to a file,
than why don't you use "amrestore"? amrestore has options to
specify what kind of image you want (compressed/uncompressed,
with/without amanda header). See man page.
Encrypting it and putting it on another tape, can then be done
using gpg and dd.

or with encryption:

Had a misty day yesterday (misty in my head).
The idea is nice, but it is not as simple as above.
Now the while loop tests for successful writing to tape,
instead of reading from the source tape until EOT. A real life
script would be much more complicated... Just forget that one.
Maybe there is some elegant solution using RAIT (never used it;
never done it).
But I still believe there is more music in a combination
of RAIT with a tape and a file driver.
If I have some more time, I really should test these features out.
