Start container from image freinet/bareos-client and add volumes to be included into your backup:

docker run -d \
  -p 9102:9102 \
  -e BAREOS_FD_PASSWORD=secret_shared_with_director \
  -v my_volume1:/volumes/my_volume \
  -v my_volume2:/volumes/my_volume2 \
  freinet/bareos-client

Create a corresponding fileset in your bareos director:

FileSet {
  Name = "my_fileset"
  Include {
    Options {
      Signature = MD5
      Compression = LZFAST
      One FS = No
    }
    File = /volumes
  }
}

Stolen from https://github.com/Brightside56/bareos-client-docker

Start container from image freinet/bareos-client and add the database to be included into your backup by using environment variables:

• BAREOS_MYSQL_USER (default is root)
• BAREOS_MYSQL_PASSWORD
• BAREOS_MYSQL_HOST (default is db)

docker run -d \
  -p 9102:9102 \
  -e BAREOS_FD_PASSWORD=secret_shared_with_director \
  -e BAREOS_MYSQL_USER=root \
  -e BAREOS_MYSQL_PASSWORD=secret \
  -e BAREOS_MYSQL_HOST=db \
  freinet/bareos-client

Create a corresponding fileset in your bareos director:

FileSet{
  Name = "mysql_stream"
  Include {
    Options {
      Signature = MD5
      Compression = LZFAST
      One FS = No
    }
    Plugin = "\\|/etc/bareos/scripts/backup-db"
  }
}

This uses the command plugin which in turn calls the script /etc/bareos/scripts/backup-db on the client. The script then looks up all available databases on the given mysql host and generates bpipe commands for each databse found...

There are two ways to restore the backup using the method described.

• Restore direct to the database
• Restore to dump files

By default, the container attempts to recover the data to the given database by first dropping each database and then recreating it from the backup.

If the container was started with the environment variable BAREOS_MYSQL_RESTORE_PATH then a compressed dump file for each database is written to the given destination.

Example to write the dumps directly to your working directory:

docker run -d \
  -p 9102:9102 \
  -e BAREOS_FD_PASSWORD=secret_shared_with_director \
  -e BAREOS_MYSQL_RESTORE_PATH=`pwd` \
  freinet/bareos-client

Note: Everything works exactly as for mysql, except for the environment variables being the standard postgres ones, and for the backup script to use in your fileset being called "backup-pg-db".

Start container from image freinet/bareos-client and add the database to be included into your backup by using environment variables:

• BAREOS_PG_USER (default for superuser is postgres)
• BAREOS_PG_PASSWORD
• BAREOS_PG_HOST

docker run -d \
  -p 9102:9102 \
  -e BAREOS_FD_PASSWORD=secret_shared_with_director \
  -e BAREOS_PG_USER=postgres \
  -e BAREOS_PG_PASSWORD=qa$$vvoRb \
  -e BAREOS_PG_HOST=db \
  freinet/bareos-client

Create a corresponding fileset in your bareos director:

FileSet{
  Name = "pgdump_stream"
  Include {
    Options {
      Signature = MD5
      Compression = LZFAST
      One FS = No
    }
    Plugin = "\\|/etc/bareos/scripts/backup-pg-db"
  }
}

Restoration is the same as well, if you don't want to restore directly to the database, set BAREOS_PG_RESTORE_PATH
