Others may address the actual backing up of the config files elsewhere.
I just want to be sure you realize that a design goal of amanda was that
no amanda software is needed to extract files from an amanda backup tape.
Standard unix utilities are all that are used in creating the tapes. So
you could:
position the tape at the start of a tape file corresponding to
the DLE you want to extract
run the tape file through a pipeline containing:
dd bs=32k skip=1 if=<tapedev>
gzip -dc # if appropriate
restore or tar or ?? # depending on which was used
Each tapefile contains a 32K "header" with information about which DLE
it contains, date, and an appropriate command line with which to extract.
