No ! No ! - doing it the way I suggested (I hesitate to call it my way -
sysadmins doing backup seriously have been doing something like that since
forever) means not pulling it from tape at all, and having a current copy
always available separate from the tape, and separate from the disk where the
files normally live. I don't think you can ever really have an accurate copy
of the index files on tape (*) because the files are being updated as each
backup is made (or not, but then they're not much use to you). Best you can
have on tape is a saved away copy of yesterday's indices.

(*) But, and there's always a but, there is a way of having them on tape. When
amanda is one, don't have her eject the last tape, but rather seek to EOM and
then put a copy of the indices in whatever format suits you on the tape. Of
course Amanda won't know about this copy of the indices. In practice, this is
about the same as using the method of doing a non-indexed Amanda backup at a
certain time, I suppose. Bottom line - indices are small, relatively
speaking. Save them somewhere convenient which is not a tape.
