Setting up borg backup (optional)
The playbook can install and configure borgbackup with borgmatic for you.
The backup will run based on matrix_backup_borg_schedule var (systemd timer calendar), default: 4am every day
Prerequisites
- Create ssh key:
ssh-keygen -t ed25519 -N '' -C matrix
- Add public part of that ssh key to your borg provider / server:
# example to append the new PUBKEY contents, where:
# PUBKEY is path to the public key,
# USER is a ssh user on a provider / server
# HOST is a ssh host of a provider / server
cat PUBKEY | ssh USER@HOST 'dd of=.ssh/authorized_keys oflag=append conv=notrunc'
Adjusting the playbook configuration
Minimal working configuration (inventory/host_vars/matrix.DOMAIN/vars.yml) to enable borg backup:
matrix_backup_borg_enabled: true
matrix_backup_borg_repository: "USER@HOST:REPO"
matrix_backup_borg_passphrase: "PASSPHRASE"
matrix_backup_borg_ssh_key: |
PRIVATE KEY
where:
- USER - ssh user of a provider / server
- HOST - ssh host of a provider / server
- REPO - borg repository name, it will be initialized on backup start, eg:
matrix - PASSPHRASE - super-secret borg passphrase, you may generate it with
pwgen -s 64 1or use any password manager - PRIVATE KEY - the content of the public part of the ssh key you created before
Check the roles/matrix-backup-borg/defaults/main.yml for the full list of available options
Installing
After configuring the playbook, run the installation command again:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
