Backup your docker volumes with borg

Detailed tutorial here.

These instructions assume you are testing things up and running everything from a single machine running on ubuntu bionic. If not you will likely need to adapt them.

Usage

git clone https://github.com/Ovski4/tutorials.git
cd docker-volume-borg-backup

Update the SSH_CONNECTION, BORG_REPO_PATH and SSH_KNOWN_HOSTS environment variables in the docker-compose.yml file according to your needs
Make sure the borg repo path exists: mkdir /home/your_user/borg_repositories
Install borg backup
Setup the SSH keys

sudo apt install openssh-server
touch ~/.ssh/authorized_keys
ssh-keygen -f ~/.ssh/id_rsa_borg_backup -t rsa -N ''
cat ~/.ssh/id_rsa_borg_backup > secret_backup_server_user_private_key.txt
chmod 400 secret_backup_server_user_private_key.txt
cat ~/.ssh/id_rsa_borg_backup.pub >> ~/.ssh/authorized_keys
chmod g-w ~
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Run docker-compose up -d. Wait for the mysql container to be initialized. You can do so by running docker-compose logs -f mysql. If you can see "MySQL init process done. Ready for start up" you are good to go. Browse http://localhost:8042/ then fill in the form like on this picture:

Hit finish setup and be patient. You should have Nextcloud running in a few minutes.

Run docker-compose logs -f backup_cron.

Every 5 minutes, you should see the following output:

backup_cron_1  | === I'm alive ===

To avoid waiting until 1AM to check if the backup runs smoothly update the docker-compose.yml file by adding the command like this:

services:
  ...
  backup_cron:
    image: ovski/borgbackup-cron:v1.0.0
    ...
    command: /var/backup_script.sh

Run docker-compose up -d and docker-compose logs -f backup_cron again. Wait for the script to end and the container to stop. You should eventually have a backup available.
Let's check it out:

cd /home/your_user/borg_repositories
borg list nextcloud

Enter your passphrase (mysuperpassphrasefortheborgnextcloudrepo). You should see the list of backups.
