I've been wondering what will happen if the backup server crashes but the tapes or the data are in good working condition. Would it be possible to recover the data using a newly installed amanda system?

Having a table of contents, and the backup is on e.g. file 12 of
the tape, and assuming gtar as backup program:

Start from e.g. some live CD, or instal the base OS enough to be able
to read a tape (eventually over the net), format new disk and:

 cd /mnt/newdisk
 mt -f /dev/nst0 rewind
 mt -f /dev/nst0 fsf 12
 dd if=/dev/nst0 bs=32k skip=1 | gtar --numeric-owner -xzpvGf -

Even the TOC can generated with a 3 line shell script.
Restoring with the amanda binaries is even more simple:

 mt -f /dev/nst0 rewind
 amrestore -p /dev/nst0 '^amandaserver.example./com$' '^/$' |
 gtar -xpGvf -
