# Very important: We suppose that your labeling of the tapes is in this format:
# configurationname-xxyyzz
# where xx is the year (e.g. 01 for 2001), yy the month and zz the day.
# If this is not true for you you'll have to adjust the script below the
# not-change-anything line ;-)

# Amanda configuration file location:
location="/usr/local/etc/amanda"
# Who is your amanda user?
amandauser="operator"
# Where is your system password file?
passwdfile="/etc/passwd"
# Where is your holding disk location?
dumpdir="/mnt/amanda/hold"
