Thats what Stefan is proposeing, a breakage of the amanda.8 manpage
into individual pages so the coverage of the individual options in
ones amanda.conf file can be discussed, along with interactions.
Thats got to be a plus IMO.

Ok, there is a link to snapshots on the main amanda.org page, which
should take you to a directory listing showing all 3 current branches
of the code. What is 2.4.5 today isn't bleeding edge, just modern.
Fist, add a user to your system called amanda, and then make this user
amanda a member of a group that pretty much has the run of the
system, like 'disk' or 'backup'. I used 'disk' myself. When thats
done, you'll have a /home/amanda directory. Download the last 2.4.5
snapshots tar.gz, and place it in the /home/amanda directory.
As root, chown amanda:disk this tar.gz file.
Become amanda with the 'su amanda' command.
Now unpack it in your home directory using 'tar xzf filenametar.gz'.
cd into the resultant directory. Read the README and INSTALL files
first for some background but don't try to build it just yet.
Copy this file I'm going to insert here, into that directory the
tarball made when you ran the 'tar xzf filename.tar.gz', and edit it
to suit your situation as far as where all the working files will be.
As amanda's indices can take several hundred megs of disk space,
choose a location with sufficient space. As /usr is usually the
biggest filesystem by far, you'll see that my example is
in /usr/local/etc, and although I've replaced drives over the years,
I've not had to move it because it was out of space. Anyway, here is
the file, which when run, checks to make sure you aren't root (thats
bad, very bad) and then builds amanda according to the options in
this file:
----------------
#!/bin/sh
# since I'm always forgetting to su amanda...
if [ `whoami` != 'amanda' ]; then
echo
echo "!!!!!!!!!!!! Warning !!!!!!!!!!!!"
echo "Amanda needs to be configured and built by the user amanda,"
echo "but must be installed by user root."
echo
exit 1
fi
make clean
rm -f config.status config.cache
./configure --with-user=amanda \
--with-group=disk \
--with-owner=amanda \
--with-gnu-ld \
--prefix=/usr/local \
--with-tapedev="FILE:/amandatapes" \
--with-debugging=/tmp/amanda-dbg/ \
--with-tape-server=coyote \
--with-amandahosts \
--with-configdir=/usr/local/etc/amanda \
--with-config=Daily \
--with-gnutar=/usr/local/bin/tar
make
-----------------------
You'll want to change the --with-tapedev= to suit where you have that
drive mounted.
You'll also want to change the --with-tape-server= to the FQDN of your
server box. What I'm using is a mistake, and it forces that alias to
be looked up in my hosts file to get the address. One can also use
the actual address there, but probably shouldn't because the machine
might get replaced and get a new address, so doing the indirection
via the use of a hostname is the preferred way.
Do a 'which tar' to find your tar and fix the --with-gnutar= line.
While you are at it, do a tar --version because there are some that
don't work. The known good ones are
tar-1.13-19
tar-1.13-25
tar-1.15
The --with-amandahosts tells it there is a seperate access control
file for amanda. See the manpages for a description. It should live
in /home/amanda/ as .amandahosts & its perms are:
-rw------- 1 amanda disk 110 Jan 17 12:02 .amandahosts
And it should look something like this:
------------
coyote.coyote.den amanda
coyote amanda
localhost.localdomain amanda
coyote.coyote.den root
------------
I'm not sure if the localhost entry is kosher. The last entry allows
root to run amrecover/amrestore. When I referred to FQDN above, the
coyote.coyote.den is the FQDN of this machine on my local network,
all in the 192.168 address block. The first string in each line s/b
changed to your server boxes FQDN and its alias which I use.
Make your version of that first file fit your system, and we'll
continue from there in the next message. Copy it back to me for
'gotcha' checking when you reply.
It might be several hours before I reply, I have a ton of yellow clay
dirt to put a shovel under, I'm working on a retaining wall while the
weather is cooperative.
