[5] Bacula – Zdalny klient

Możliwe jest dodanie zdalnych hostów jako kopii zapasowych klientów docelowych.

Ten przykład jest oparty na środowisku, jak poniżej.

[1] Skonfiguruj podstawowy Bacula Server, patrz tutaj.

[2] Zainstaluj komponent File na nowym zdalnym hoście klienta Bacula.

[root@vlsr02 ~]# dnf install bacula-client bacula-console

[3] Na serwerze Bacula, jeśli Firewalld jest uruchomiony, zezwól na usługę.

[root@vlsr01 ~]# firewall-cmd --add-service=bacula --permanent
[root@vlsr01 ~]# firewall-cmd –reload

[4] Na kliencie Bacula, jeśli Firewalld jest uruchomiony, zezwól na usługę.

[root@vlsr02 ~]# firewall-cmd --add-service=bacula-client --permanent
[root@vlsr02 ~]# firewall-cmd –reload

[5] Skonfiguruj serwer Bacula.

[root@vlsr01 ~]# mcedit /etc/bacula/bacula-dir.conf
# dodaj na końcu
# zdefiniuj zadanie
JobDefs {
Name = "Job-vlsr02"
Type = Backup
Level = Full
# wpisz [Name] w sekcji [Client]
Client = vlsr02
# wpisz [Name] w sekcji [FileSet]
FileSet = "VLSR02 Set"
Schedule = "WeeklyCycle"
Storage = File1
Messages = Standard
Pool = File
SpoolAttributes = yes
Priority = 10
Write Bootstrap = "/var/spool/bacula/%c.bsr"
}
# zdefiniuj zadanie kopii zapasowej
Job {
Name = "vlsr02-BackupClient"
# wpisz [Name] w sekcji [Client]
Client = vlsr02
# wpisz [Name] w sekcji [JobDefs]
JobDefs = "Job-vlsr02"
}
# zdefiniuj zestaw File
FileSet {
Name = "VLSR02 Set"
Include {
Options {
signature = MD5
Compression = GZIP
}
# docelowy katalog do bakupu
File = /etc
}
}
# zdefiniuj klienta
Client {
Name = vlsr02
# hostname lub adres IP klienta
Address = vlsr02.zicher.lab
FDPort = 9102
Catalog = MyCatalog
# hasło demona File
Password = "TajneHasło"
File Retention = 60 days
Job Retention = 6 months
AutoPrune = yes
}

[root@vlsr01 ~]# systemctl restart bacula-dir

[6] Skonfiguruj klienta Bacula.

[root@vlsr02 ~]# mcedit /etc/bacula/bacula-fd.conf
Director {
Name = bacula-dir
# linia 19: hasło demona File
Password = "TajneHasło"
}
. . . . .
# linia 28: hasło tray-monitor’a
Director {
Name = bacula-mon
Password = "TajneHasło"
Monitor = yes
}

[root@vlsr02 ~]# mcedit /etc/bacula/bconsole.conf
Director {
Name = bacula-dir
DIRport = 9101
# hostname lub adres  IP demona Director
address = vlsr01.zicher.lab
# hasło demona Director
Password = "TajneHasło"
}

[root@vlsr02 user01]# systemctl enable --now bacula-fd

[7] W porządku. Możliwe jest uruchomienie operacji tworzenia kopii zapasowej i przywracania zarówno na serwerze, jak i na kliencie.

Dla przykładu uruchom tworzenie kopii zapasowej i przywracanie na hoście klienta.
