bacula를 이용한 online 백업 시스템 환경 구축하기 [1]
발췌 : http://www.cep.kr/blog/cep/239
bacula를 설치하기위해서는 다음 몇가지가 필요하다. ( bin & devel package )
readline package
mysql package ( 다른 DB package여도 된다.)
– mysql server를 위해 perl-DBD-MySQL package도 필요
python package
start mysql daemon
[] Bacula-5.0.2 install
download : http://www.bacula.org
extract : tar zxvf bacula-x.x.x.tar.gz
configure : ./configure –prefix=/usr/local/bacula-5.0.2 –with-x –with-mysql –with-readline –with-python –with-db-password=BACULA_PWD –with-db-port=3306 –enable-includes –enable-bwx-console –enable-static –enable-shared
mysql port is 3306.
make : make
install : make install
환경설정하기 : bacula server
cd /usr/local/bacula-5.0.2/etc
#환경설정 했던것을 다시한번 보고 싶을때
./bacula_config
#create bacula database to mysql
./create_bacula_datase
#create bacula table to mysql
./make_bacula_tables
#copy from <bacula source>/examples/sample-query.sql to /usr/local/bacula-5.0.2/etc/query.sql
cp /root/bacula-5.0.2/examples/sample-query.sql to /usr/local/bacula-5.0.2/etc/query.sql
checking /etc/service
[root@backup bacula-5.0.2]# cat /etc/services |grep bacula
bacula-dir 9101/tcp # Bacula Director
bacula-dir 9101/udp # Bacula Director
bacula-fd 9102/tcp # Bacula File Daemon
bacula-fd 9102/udp # Bacula File Daemon
bacula-sd 9103/tcp # Bacula Storage Daemon
bacula-sd 9103/udp # Bacula Storage Daemon
run : cd /usr/local/bacula-5.0.2/sbin
./bacula start
./console (or ./gnome-console)
stop : ./bacula stop
checking bacula stuff
# ps -ef |grep bacula

# ./bacula status
bacula-sd (pid 18753) is running…
bacula-fd (pid 18763) is running…
bacula-dir (pid 18771) is running…
그러나 bconsole을 띄우면 bacula-dir 데몬이 죽게된다. 그래서 netstat로 9101 포트가 살아 있는지 확인을 꼭해야 한다.
# ./bacula status
bacula-sd (pid 2040) is running…
bacula-fd (pid 2050) is running…
bacula-dir dead but pid file exists
이것은 대게 mysql과 bacula와 연동이 안되서 생기는 증상이다.
# ./bacula stop
# mysql

이렇게 label 명령어로 백업 시킬 device (file name)을 생성시킨후에 run 명령어로 백업하면 백업될곳의 내용이 label로 정의 한 파일에 저장된다.
[] bacula daemon 설명
bacula director (bacula-dir)
– backup, restore 등의 작업을 총괄하는 서비스
– backup schedule을 관리
bacula console (console)
– 관리자가 명령어를 입력하는 콘솔 (director에 접속할수 있어야함)
– bwx-console은 GUI 환경의 console
bacula file (bacula-fd)
– 백업할 곳의 장비에 설치되는 서비스
– director로부터 명령어를 받아서 backup 하거나 restore를 해준다.
– restore를 할때 다른곳으로도 보내서 restore가 가능하다.
bacula storage (bacula-sd)
– backup device를 갖고 있는 장비에 설치되는 서비스
– bacula-fd로부터 날아오는 파일을 저장 하거나
backup된 것으로부터 bacula-fd로 데이터를 날려주는 daemon
– directory에 file device를 사용하거나 DVD, DLT, 8mm, 4mm 등의 device 정의
– director로부터 명령어를 받아 처리함.
Catalog
– 백업되는 파일들의 정보가 저장되는 데이터베이스 머신에 설치되는 서비스
– 이것이 깨진경우 백업파일이 직접 접근할수 있는 유틸을 사용가능
bacula monitor
– 여러 버시스들의 상태를 알수 있는 GUI 프로그램
