Is there a way of creating a copy or image file of the data, that's already 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).
