Written by
Updated at May 7, 2025

You can use Bacula to backup and recover your VM in Yandex Object Storage.

Bacula consists of multiple components:

  • Bacula Director: Manages backup and recovery.
  • File Daemon: Provides access to backup files.
  • Storage Daemon: Reads files and writes them to the hard disk.
  • Catalog: Maintains the backup file catalog that resides in the MariaDB database.
  • Bacula Console: Management console for working with Bacula Director.

To configure Bacula backup and recovery:

  1. Get your cloud ready.
  2. Create a VM.
  3. Configure the AWS CLI.
  4. Install Bacula and additional components.
  5. Configure MariaDB.
  6. Configure a storage.
  7. Configure the Bacula components.
  8. Create a backup.
  9. Recover the files.

If you no longer need the resources you created, delete them.

Getting started

Sign up in Yandex Cloud and create a billing account:

  1. Navigate to the management console and log in to Yandex Cloud or register a new account.
  2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one and link a cloud to it.

If you have an active billing account, you can navigate to the cloud page to create or select a folder for your infrastructure to operate in.

Learn more about clouds and folders.

The backup and recovery support costs include:

Create a bucket

To create a backup bucket in Object Storage:

  1. Navigate to the Yandex Cloud management console and select the folder to work with.
  2. On the folder dashboard, click Create resource and select Bucket.
  3. In the ** Name** field, specify the bucket name.
  4. Set public access to read objects in the bucket, get an object list, and read bucket settings, i.e., Restricted.
  5. In the Storage class field, select Cold.
  6. Click Create bucket.

Create a service account

Create a service account and assign the editor role to it.

Create static access keys

Create static access keys.

Save key_id and the secret key. You will not be able to get the secret key again.

Create a VM

To create a VM:

  1. In the management console, select the folder where you will create your VM.

  2. From the list of services, select Compute Cloud.

  3. In the left-hand panel, select Virtual machines.

  4. Click Create virtual machine.

  5. Under Boot disk image, select a public CentOS 7 image.

  6. Under Location, select the availability zone where your VM will reside.

  7. Under Computing resources, navigate to the Custom tab and specify these settings:

    • Platform: Intel Ice Lake
    • vCPU: 2
    • Guaranteed vCPU performance: 20%
    • RAM: 2 GB

  8. Under Network settings:

    • In the Subnet field, enter the ID of a subnet in the new VM’s availability zone. Alternatively, select a cloud network from the list.

      • Each network must have at least one subnet. If there is no subnet, create one by selecting Create subnet.

      • If you do not have a network, click Create network to create one:

        • In the window that opens, enter the network name and select the folder where the network will reside.
        • Optionally, enable the Create subnets setting to automatically create subnets in all availability zones.
        • Click Create network.

    • In the Public IP address field, select Auto to assign a random external IP address from the Yandex Cloud pool to the VM. Alternatively, select a static address from the list if you reserved one.

  9. Under Access, select SSH key and specify the VM access credentials:

    • In the Login field, enter a name for the user you want to create on the VM, e.g., yc-user.

      Alert

      Do not use root or other reserved usernames. To perform operations requiring root privileges, use the sudo command.

    • In the SSH key field, select the SSH key saved in your organization user profile.

      If there are no saved SSH keys in your profile, or you want to add a new key:

      • Click Add key.
      • Enter a name for the SSH key.
      • Upload or paste the contents of the public key file. You need to create a key pair for the SSH connection to a VM yourself.
      • Click Add.

      The SSH key will be added to your organization user profile.

      If users cannot add SSH keys to their profiles in the organization, the added public SSH key will only be saved to the user profile of the VM being created.

  10. Under General information, specify the VM name: bacula-vm.

  11. Click Create VM.

  12. Wait until the VM status switches to RUNNING.

Configure the AWS CLI

To configure the AWS CLI on bacula-vm:

  1. In the management console, navigate to the VM page and get the VM’s public IP address.

  2. Connect to the VM over SSH.

    We recommend using a key pair when authenticating over SSH. Configure the generated key pair so that the private key matches the public key the VM got.

  3. Update the packages on the system by running this command in the terminal:

    yum update -y

  4. Install the AWS CLI:

    yum install awscli -y

sudo chmod -R 700 /tmp/bacula
sudo semanage permissive -a bacula_t

Mount the bucket to the file system

  1. To upload backups to Object Storage, mount the s3fs bucket by running the command below and specifying the bucket name:

    sudo s3fs <bucket_name> /tmp/bacula \
  -o url=https://storage.yandexcloud.net \
  -o use_path_request_style \
  -o allow_other \
  -o nonempty \
  -o uid=133,gid=133,mp_umask=077

    Where:

    • uid=133: bacula user ID from the /etc/passwd file.
    • gid=133: bacula group ID from the /etc/passwd file.

  2. Check the access permissions for the /tmp/bacula folder:

    sudo ls -la /tmp/bacula/

    Result:

    drwx------.  2 bacula bacula        31 Sep 18 09:16 .
drwxrwxrwt. 10 root   root         265 Sep 18 08:59 ..

  3. Make sure the bacula user can create files in the /tmp/bacula folder:

    1. Enable the bash shell for the bacula user:

      sudo sed -i "/^bacula/ s@/sbin/nologin@/bin/bash@" /etc/passwd

    2. In the /tmp/bacula folder, create a file:

      sudo runuser -l  bacula -c 'touch /tmp/bacula/test.test'

    3. Make sure you have created the test.test file in the /tmp/bacula folder:

      sudo ls -la /tmp/bacula | grep test.test

    5. Delete the test file:

      sudo runuser -l  bacula -c 'rm -f /tmp/bacula/test.test'

    6. Disable the bash shell for the bacula user:

      sudo sed -i "/^bacula/ s@/bin/bash@/sbin/nologin@" /etc/passwd

Configure the Bacula components

Configure Bacula Director

  1. Open the Bacula Director configuration file:

    sudo nano /etc/bacula/bacula-dir.conf

  2. To set up a connection to Bacula Director, add the DirAddress = 127.0.0.1 line in the Director configuration section:

    ...
Director {                              # define myself
  Name = bacula-dir
  DIRport = 9101                        # Specify the port (a positive integer) on which the Director daemon will listen for Bacula Console connections.
                                        # This same port number must be specified in the Director resource of the Console configuration file.
                                        # The default is 9101, so normally this directive need not be specified.
                                        # This directive should not be used if you specify the DirAddresses (plural) directive.
  QueryFile = "/etc/bacula/query.sql"
  WorkingDirectory = "/var/spool/bacula"
  PidDirectory = "/var/run"
  Maximum Concurrent Jobs = 1
  Password = "@@DIR_PASSWORD@@"         # Console password
  Messages = Daemon
  DirAddress = 127.0.0.1
}    
...

  3. For your convenience, rename the BackupClient1 task to BackupFiles:

    ...
Job {
  Name = "BackupFiles"
  JobDefs = "DefaultJob"
}
...

  4. To assign /tmp/bacula-restores as the folder for your recovered files, add the Where = /tmp/bacula-restores line to the RestoreFiles job configuration section:

    ...
Job {
  Name = "RestoreFiles"
  Type = Restore
  Client=bacula-fd
  FileSet="Full Set"
  Storage = File
  Pool = Default
  Messages = Standard
  Where = /tmp/bacula-restores
}
...

  5. Under Include in the FileSet configuration section:

    • Add the compression = GZIP line to the Options section to enable backup compression.
    • Specify File = / to back up the entire file system.
    ...
FileSet {
  Name = "Full Set"
  Include {
	Options {
	  signature = MD5
	  compression = GZIP
	}
	File = /
  }
  Exclude {
	File = /var/spool/bacula
	File = /tmp
	File = /proc
	File = /tmp
	File = /.journal
	File = /.fsck
  }
}
...

  6. In the management console, navigate to the VM page and get the VM’s internal IP address.

  7. To set up an outbound connection to the Storage Daemon, specify the VM’s internal IP address in the Address field of the Storage configuration section:

    ...
Storage {
  Name = File
# Do not use "localhost" here
  Address = <VM_internal_IP_address>  # N.B. Use a fully qualified name here
  SDPort = 9103
  Password = "@@SD_PASSWORD@@"
  Device = FileStorage
  Media Type = File
}
...

  8. To connect to the DB, specify dbpassword = "bacula_db_password" that you created when setting up MariaDB in the Catalog configuration section:

    ...
# Generic catalog service
Catalog {
  Name = MyCatalog
# Uncomment the following line if you want the dbi driver
# dbdriver = "dbi:postgresql"; dbaddress = 127.0.0.1; dbport =
  dbname = "bacula"; dbuser = "bacula"; dbpassword = "bacula_db_password"
}
...

  9. Save the file.

  10. Make sure the bacula-dir.conf file has no syntax errors:

    sudo bacula-dir -tc /etc/bacula/bacula-dir.conf

    If there are no error messages, the configuration is correct.

Configure Storage Daemon

  1. Open the Storage Daemon configuration file:

    sudo nano /etc/bacula/bacula-sd.conf

  2. To set up an outbound connection to the Storage Daemon, specify the VM’s internal IP address in the SDAddress field of the Storage configuration section:

    ...
Storage {                                      # definition of myself
  Name = BackupServer-sd
  SDPort = 9103                                # Specifies port number on which the Storage daemon listens for Director connections. The default is 9103.
  WorkingDirectory = "/var/spool/bacula"
  Pid Directory = "/var/run/bacula"
  Maximum Concurrent Jobs = 20
  SDAddress = <VM_internal_IP_address>         # This directive is optional, and if it is specified,
                                               # it will cause the Storage daemon server (for Director and File daemon connections) to bind to the specified IP-Address,
                                               # which is either a domain name or an IP address specified as a dotted quadruple.
                                               # If this directive is not specified, the Storage daemon will bind to any available address (the default).
}
...

  3. In the Device configuration section, specify Archive Device = /tmp/bacula as the backup folder:

    ...
Device {
  Name = FileStorage
  Media Type = File
  Archive Device = /tmp/bacula 
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = no;
  AlwaysOpen = no;
}
...

  4. Save the file.

  5. Make sure the bacula-sd.conf file has no syntax errors:

    sudo bacula-sd -tc /etc/bacula/bacula-sd.conf

    If there are no error messages, the configuration is correct.

Create passwords for the Bacula components

Bacula Director, the Storage Daemon, and the File Daemon all use passwords for cross-component authentication.

To set passwords for the Bacula components:

  1. Generate passwords for Bacula Director, the Storage Daemon, and the File Daemon:

    DIR_PASSWORD=`date +%s | sha256sum | base64 | head -c 33`
SD_PASSWORD=`date +%s | sha256sum | base64 | head -c 33`
FD_PASSWORD=`date +%s | sha256sum | base64 | head -c 33`

  2. Store the passwords in the configuration files:

    sudo sed -i "s/@@DIR_PASSWORD@@/${DIR_PASSWORD}/" /etc/bacula/bacula-dir.conf
sudo sed -i "s/@@DIR_PASSWORD@@/${DIR_PASSWORD}/" /etc/bacula/bconsole.conf
sudo sed -i "s/@@SD_PASSWORD@@/${SD_PASSWORD}/" /etc/bacula/bacula-sd.conf
sudo sed -i "s/@@SD_PASSWORD@@/${SD_PASSWORD}/" /etc/bacula/bacula-dir.conf
sudo sed -i "s/@@FD_PASSWORD@@/${FD_PASSWORD}/" /etc/bacula/bacula-dir.conf
sudo sed -i "s/@@FD_PASSWORD@@/${FD_PASSWORD}/" /etc/bacula/bacula-fd.conf
