Create an amanda xinetd entry
Code:

sudo vim /etc/xinetd.d/amanda

Give it the following contents
Code:

# default: on
# description: The amanda service
service amanda
{
only_from            = ubunutlinux.co.in
disable                  = no
socket_type         = dgram
protocol                = udp
wait                        = yes
user                        = backup
group                     = backup
groups                   = yes
server                     = /usr/lib/amanda/amandad
server_args           = -auth=bsd amdump amindexd amidxtaped
}
service amandaidx
{
socket_type             = stream
protocol                    = tcp
wait                            = no

user                             = backup
group                          = backup
groups                        = yes
server                          = /usr/lib/amanda/amindexd
disable                        = no
}
service amidxtape
{
socket_type             = stream
protocol                   = tcp
wait                           = no
user                           = backup
group                       = backup
groups                     = yes
server                       = /usr/lib/amanda/amidxtaped
disable                     = no
}

Install the AMANDA Server

Install AMANDA and dependencies

sudo apt-get install amanda-server

Restart xinetd

sudo /etc/init.d/xinetd restart

Become “backup” user

su backup

Create copies of the configuration files, just in case

cp -R /etc/amanda/DailySet1 /etc/amanda/DailySet1.bak

Edit amanda.conf

Let’s get in and edit the amanda.conf
Code:

vim /etc/amanda/DailySet?1/amanda.conf

Make the following changes in the file
Code:

org “”
mailto “backupadmin@ubuntulinux.co.in ”
tpchanger “chg-disk”
changerfile “/etc/amanda/daily/changer”
tapedev “file:/amandabackup/DailySet1/slots”
tapetype HARDDISK
#tapetype HP-DAT   <— comment this out
#labelstr “^HISS[0-9][0-9]*$”           <— comment this out
amrecover_do_fsf yes
amrecover_check_label yes
amrecover_changer “changer”
define tapetype HARDDISK {
length  mbytes
}

Dumptypes are deinfed in /etc/amanda/amanda.conf, but we’ll use the GNUTAR dumptype “comp-user-tar” for this example

Let’s get in and edit the disklist
Code:

vim /etc/amanda/DailySet1/disklist

Add a line like so
Code:

ubuntulinux.co.in /Project comp-user-tar

ubuntlinux.co.in  /clientbackup comp-user-tar

What this line is telling AMANDA is that when it attempts to do a dump that it should connect to ubuntlinux.co.in, backup the directory /project and /clientbackup and user the options that are defined in amanda.conf for the “comp-user-tar” dumptype.

Create Virtual Tapes

Choose a location for your tapes to reside

Create the tapelist file that is necessary for indexing tapes available
Code:

touch /etc/amanda/DailySet1/tapelist

Create the location and set permissions for the virtual tapes
Code:

mkdir -p -m 770 /amandabackup/DailySet1/slots

chown -R backup:backup /amdndahosts

CD to the new directory

cd /amandabackup/DailySet1/slots

Create the necessary directories for the tapes
Code:

for (i=1; $i<=25; i++)?; do mkdir slot$i; done

Create symlink for the data directory to point to the first tape
Code:

ln -s slot1 data

Test the vtapes to be sure that we get an ONLINE message
Code:

ammt -f file:/amandabackup/DailySet?1/slots status

Label the tapes

for (i=1; $i<=9; i++)?; do amlabel DailySet1 DailySet?1-0$i slot $i; done

for (i=10; $i<=25; i++)?; do amlabel DailySet1 DailySet?1-$i slot $i; done

Output should look like (for each slot)

labeling tape in slot 1 (file:/amandabackup/DailySet?1/slots)
rewinding, reading label, not an amanda tape
rewinding, writing label DailySet?1-01, checking label, done.

Reset the changer back to slot 1

amtape DailySet1 reset

Output should look like

amtape: changer is reset, slot 1 is loaded.

Edit .amandahosts

On Ubuntu the .amandahosts file is located as /etc/amandahosts

Open the file

vim /etc/amandahosts

The file looks like

ubuntlinux.co.in backup amindexd amidxtaped
ubuntlinux.co.in root amindexd amidxtaped
