With respect to having the current amanda directory backed up, what I do is simply run scripts from
a crontab entry:
45 22 * * * /usr/local/adm/backup/daily-amanda;
/usr/local/adm/backup/daily-amanda-config
The first script runs amanda and then runs a script I wrote called amchanger that accesses the tape
library and unloads the tape that amanda just wrote to. The second script in the crontab entry does
incremental and full backups of the amanda home directory on a weekly cycle to another server using
cpio. The semicolon in the crontab entry says to wait until the first one is completed before
calling the second one. I get an email report from amanda when the backups are done, and I get an
email report from cron when the scripts are all completed, because they generate output to standard
output.
Running on Ubuntu these days. Originally set up on Solaris.
I think all of this and details are back in the list archives somewhere.
Possibly on the wiki as well.

is there a way to run a user supplied program just

before it actually opens and creates a new file on

Do I recall correctly that it opens a tmp file on
the vtape and when complete renames it? Or am I
thinking of the chunks on the holding disk?

My GenesAmandaHelper does not do anything to the vtape, all it does is
run amanda as a child so it knows when amanda is done. at which point it
does its thing copyiing the now uptodate indices and configs to that
same vtape amanda just made. so they are valid for the vtape just
remade, as opposed to always being a day out of date.
No one else has publicly discussed how they've handled that so I have no
clue what others are doing, if anything to prevent a days indexes loss
if the drive or the amandatapes drive pukes and you have to recover to
bare metal. I also delete from the index database I keep, those files
that represent a vtape that has been re-used. So I have a duplicate of
amandas index stuff that takes up a few gigabytes on the main drive in
addition to a backup copy on the vtape. Belt and suspenders approach.
Recovering the latest indice and putting it where amanda keeps them,
enables access to the whole /amandatapes drive in one swell foop.
