chkconfig xinetd on

service xinetd restart

Note: Make sure the service is running or not

# netstat -a | grep amanda
udp        0      0 *:amanda                    *:*

3. Set password for the amandabackup user:
# passwd amandabackup
****
****

4. Create a directory for our vtapes, and set its ownership and permissions:

# mkdir -p /data/amanda/vtape/DailySet1

# chown amandabackup:disk /data/amanda/vtape/DailySet1

# chmod -R 750 /data/amanda/vtape/DailySet1

5. change to user and run the command:

# su – amandabackup

-bash-4.1$ amserverconfig DailySet1 –template harddisk –tapedev /data/amanda/vtape/DailySet1 –mailto root@localhost –dumpcycle 1week –runspercycle 5 –tapecycle 12 –runtapes 1 

6. from root user:

# cp /var/lib/amanda/example/xinetd.amandaserver /etc/xinetd.d/amandaserver

Note: Because, server has been configured, copy the amandaserver config file of Xinetd to its correct path.

Step C: Amanda Server:

11. Add the client at server system. We are going to add the client 192.168.1.62 to backup the “/root” for client to DailySet1 tapes.
Run the command from ‘amandabackup’ user:
bash-4.1$ amaddclient –config DailySet1 –client 192.168.1.62 –diskdev /root –dumptype comp-user-tar

12. Copy file from ‘root’ user:

# cp /var/lib/amanda/example/xinetd.amandaclient /etc/xinetd.d/amandaclient

Note: Because, we have added a client, now copy the amandaserver config file of Xinetd to its correct path.

13. Add client system in server /etc/hosts file:

# echo “192.168.1.62 samba.example.com” >> /etc/hosts

14. Adding client to servers amandahost:

# echo “samba.example.com root amindexd amidxtaped” >> /var/lib/amanda/.amandahosts

15. Login from amandabackup user:

-bash-4.1$ amcheck DailySet1

DONE

16. Taking the backup of the client:
-bash-4.1$ amdump DailySet1

Note: it will be at /data/amanda/vtape/DailySet1/

Step B: Amanda Client:

7. Download the package and install the client:

# wget http://www.zmanda.com/downloads/community/Amanda/3.3.3/Redhat_Enterprise_6.0/amanda-backup_server-3.3.3-1.rhel6.x86_64.rpm

8. Set password for the amandabackup user:
# passwd         amandabackup
****
****

9. To recover on a Linux client, you must first specify the tape device on the server to use. In each Linux clients we change the file /etc/amanda/amanda-client.conf

Change this line:

tapedev “tape:/dev/YOUR-TAPE-DEVICE-HERE” # your tape device

to this:

tapedev “file://data/amanda/vtape/DailySet1″ # your tape device

10. Add the amanda server to clients /etc/hosts file:
192.168.1.64   amanda.example.com            amanda
