Hi all
Please note this is just "phase 1" basis for discussion ;-)
It should cover all setups to be done on the server prior to the final
amanda setup.
So hopefully ;-) If you have done this you can just edit your amnda
config files and off you go !!!
Please look @ the following.
Is evereything in logical order? (I wrote as I went along)
Have I left enything out?
Have you got something to add ?
All contributions are welcome
Tnx

building and installing amanda for network backups
---------------------------------------------------
Please remember this is a newbie "quick&dirty" setup HOWTO
a)Thanx
Firstly thanx to the amanda users mailing listand evereybody there who
answered my questions so
patiently,without you guys I wouldn't have been able to do this.
b)Disclaimer
This worked for me.If you machie starts smoking or bursts into
flames,sorry I cannot do anything about it.
Should this happen please post to the list as I am sure evereyone would
like to hear about it,include a full
bugreport please ;-)
c)Setup
I use the following here
user=amanda
group=backup
profile=test
index machine=tapehost
I use Red-Hat 7.3 on x86
I have:
two ide harddrives
scsi Tandberg VS80 DLT tapedrive (internal)
Subsystem: Adaptec 29160 Ultra160 SCSI Controller
Make sure your kernel supports your scsi cotroller,how to setup that
is way beyond the scope of this document.
Use the link below to test your tapedrive.It is for DLT scsi.
If you use auto changers or robotics Sorry I do not have one to test
on ;-)
When you can use the mt utility on the tapedrive you are ready for
primetime!!!
To setup the DLT Tapedrive I found this link verey handy

---------------------------------------------------------------
d)On index machine (where tape device is)
adduser amanda
groupadd backup
./configure --with-user=amanda --with-group=backup
make
make install
@ this point I like to switch off hardware compression
#mt -t /dev/nst0 -compression 0
I actually put that into my rc.local file to make sure.
As someone mentioned on the list amanda measures the output after
compression so you should score a lot
by doing this
Put the Amanda services into your /etc/services file on the tapehost
Add entries like so:
amanda 10080/udp
amandaidx 10082/tcp
amidxtape 10083/tcp
I just added them right @ the top
Add the following to your xinetd.d directory
vi amanda
cut&paste the following
--------------------------------------------------------------------
service amanda
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = amanda
group = backup
groups = yes
server = /usr/local/libexec/amandad
}
----------------------------------------------------------------------
vi amandaidx
cut&paste the following
-----------------------------------------------------------------------
service amandaidx
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = amanda
group = backup
groups = yes
server = /usr/local/libexec/amindexd
}
-------------------------------------------------------------------------
vi amidxtape
cut&paste the following
--------------------------------------------------------------------------
service amidxtape
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = amanda
group = backup
groups = yes
server = /usr/local/libexec/amidxtaped
}
-------------------------------------------------------------------------
now we must get our config directory ready
mkdir /usr/local/etc/amanda/test
In the above test is the name of my profile stick to it for now but when
you setup your own
you can use whatever you want.
Now we copy the files we need into the config directory
cd ~/amanda-2.4.2p2/example/
cp amanda.conf config.site disklist
Make amanda the owner
chown amanda:backup /usr/local/etc/amanda/test
Now create the log directory
mkdir /usr/local/var/amanda
mkdir /usr/local/var/amanda/test
mkdir /usr/local/var/amanda/test/curinfo
mkdir /usr/local/var/amanda/test/index
mkdir /usr/local/var/amanda/test/tapelist
Make amanda the owner
chown -R amanda:backup /usr/local/var/amanda/test/
We will later edit the amanda.conf file to reflect this.
Now let's setup our holding area for images while they are waiting to be
written to tape
mkdir /var/dump
Make amanda the owner
chown -R amanda:backup /var/dump
We will later edit the amanda.conf file to reflect this.
------------------------------------------------------------------------------------------------------------
e)On client
adduser amanda
groupadd backup
./configure --with-user=amanda --with-group=backup --without-server
--with-index-server=indexhost
make
make install
Now client side setup
create you /home/amanda/.amandahost file
vim /home/amanda/.amandahost
enter this in there
<indexhost.domainname.com> amanda (where indexhost is the fully
qualified domain name of your backup server)
do this for tapehost to so you can backup it.
/etc/dumpdates was allready setup and had the correct group (disk)
Make raw disk devices readable by dumpuser.
