That'd be a nice feature, but then a lot of things about time travel might
be nice :-) I don't think it can be done in the general case, because taping
will usually have started before the indices would be updated.

Of course in the case of an emergency such that you need to get the indices
from tape, I suppose having on on the last tape a copy of the indices
correct as to the previous tape would be a whole lot better than nothing.

What I, and I think many others, do is to copy the indices to a different
disk after each daily Amanda run which gives you a little insurance against
a disk crash. As I write this it occurs to me that the indices are not so
big that it would be unreasonable to also ship them offsite somewhere also,
presuming that you have access to such a place. You could even simply email
them to youself at a special account on a non-company mailserver.
