Virtual Server: How to Install and Configure Backups (Bacula) on a RHEL Server
SUMMARY
The Bacula Enterprise Edition (BEE) backup service is the optional daily backup service listed in the page. Backups are file level only.
If you are a virtual server customer and have purchased the daily backup service, a BEE client will need to be configured on your server to communicate with the backup server. This article describes installing and configuring the BEE client on a Red Hat Enterprise Linux (RHEL) virtual server.
PREREQUISITES
- You should already have the daily backup service purchased through ITS Managed Services. If you have not already done so, please contact ITS Managed Services at itscs@hawaii.edu to do so.
PROCEDURE
Do the following to install a BEE client on your RHEL virtual server:
- Contact ITS Managed Services at itscs@hawaii.edu asking that the latest version of the BEE client .rpm packages be file dropped to you (via the service). Once you have these files, upload them to your virtual server's /root directory.
- Log into your virtual server and switch user to the root user.
- Install the BEE client software:
# cd /root
# yum install -y ./bacula-enterprise-*.rpm
NOTE: You may need to install the bacula-enterprise-lib-*.rpm file first before installing the bacula-enterprise-client-*.rpm file.
- Modify the /opt/bacula/etc/bacula-fd.conf file (installed when you install the BEE client) as outlined in the following example. In this example, "bac10" is used as the hostname, but for your server, it should be the short hostname of your virtual server.
(a) Change this:
Director {
Name = bac10-dir
Password = "< random_password_1 >"
}
To this (change the Name and use the randomly generated password, or create your own):
Director {
Name = bacula-dir
Password = "<random-password>"
}
(b) Change this:
Director {
Name = bac10-mon
Password = "a long random password"
Monitor = yes
}
To this (comment out all lines by prefixing them with a "#"):
#Director {
# Name = bacula-dir-mon
# Password = "a long random password"
# Monitor = yes
#}
(c) Change this:
FileDaemon { # this is me
Name = bac10-fd
FDport = 9102 # where we listen for the director
WorkingDirectory = /opt/bacula/working
Pid Directory = /opt/bacula/working
Maximum Concurrent Jobs = 20
Plugin Directory = /opt/bacula/plugins
}
To this (remove "-fd" from shortname of the host. Change Maximum Concurrent Jobs to 20):
FileDaemon { # this is me
Name = bac10
FDport = 9102 # where we listen for the director
WorkingDirectory = /opt/bacula/working
Pid Directory = /opt/bacula/working
Maximum Concurrent Jobs = 20
Plugin Directory = /opt/bacula/plugins
}
(d) Change this:
Messages {
Name = Standard
director = bac10-dir = all, !skipped, !restored, !saved
}
To this (change director name):
Messages {
Name = Standard
director = bacula-dir = all, !skipped, !restored, !saved
}
- Enable automatic start of the BEE client upon server boot:
RHEL 8: # systemctl enable bacula-fd
- Restart bacula-fd service:
RHEL 8: # systemctl start bacula-fd
- Run the following command to allow port 9102 incoming for the backup traffic:
firewall-cmd --permanent --zone=public --add-port=9102/tcp && firewall-cmd --reload.
- (Optional) If TCP Wrappers is configured in the OS, add a rule to allow incoming connections from the Bacula Director Server dr-dir12.pvt.hawaii.edu. E.g., modify the /etc/hosts.allow file to add the line "ALL: 172.24.100.11 dr-dir12.pvt.hawaii.edu").
- (Optional) Delete the bacula-enterprise-* .rpm files from /root.
- Notify IT TI-Applications that you have completed installing the BEE client on your virtual server. Please let us know the name of your virtual server, which directories you want backed up, and an estimate of you much storage space you expect the backup to require. Do not include the Bacula password in this email. If it is emailed in clear text, you will be required to change the password. A staff member from Contract Services will respond to you and ask you to send the password you made note of in step 4b above via the service.
