I once wrote about a small shellscript that I use to back up
AMANDA-metadata and have received some requests to provide it here.
At last I have found some time to translate it to english and add some
small notes. I use this script regularly in some client-setups by
wrapping it into rundump.sh (which is triggered by cron).
The idea is to run amdump first, after that generate tarballs of the
current configs, indexes etc. These tarballs can then be synced
somewhere else, sent by mail or simply kept for reference (although it
is recommended to get them off your AMANDA-server ...)
The script am_meta_bkp.sh is far from being perfect, but it is a draft
that works pretty well for me. The scripts were written on a
Suse-Linux-system and uses linux-specific paths etc.
Feel free to add comments and patches.
I will also add this script and its mutations to the AMANDA-patches
page, if noone flames me for bad scripting ;-)
Greets, Stefan.

# This script backs up AMANDA-metadata like indexes and config-files.
# It creates files in the directory TARGETPATH, the filenames start with
# the string HEADER_STRING, this string contains the timestamp TIMESTAMP.
# The files backed up belong to the AMANDA-configuration CONFIG, for
# proper reading of the relevant parameters it is necessary to provide
# the correct username AMUSER of the AMANDA-user.
# Backup-files older than 7 days are removed.
#
# Backed up files:
# - curinfo-DB
# - index-DB
# - config-dir (eg. /usr/local/etc/amanda/daily)
# - logfiles
#
