# Ansible Role: BorgBackup Client
[![Test](https://github.com/borgbase/ansible-role-borgbackup/actions/workflows/main.yml/badge.svg)](https://github.com/borgbase/ansible-role-borgbackup/actions/workflows/main.yml) [![Ansible Galaxy](https://img.shields.io/ansible/role/48519)](https://galaxy.ansible.com/m3nu/ansible_role_borgbackup)
[![Test](https://github.com/borgbase/ansible-role-borgbackup/actions/workflows/main.yml/badge.svg)](https://github.com/borgbase/ansible-role-borgbackup/actions/workflows/main.yml) [![Ansible Galaxy](https://img.shields.io/ansible/role/48519)](https://galaxy.ansible.com/borgbase/ansible_role_borgbackup)
Set up encrypted, compressed and deduplicated backups using [BorgBackup](https://borgbackup.readthedocs.io/en/stable/) and [Borgmatic](https://github.com/witten/borgmatic). Currently supports Debian/Ubuntu, CentOS/Red Hat/Fedora, Archlinux and Manjaro.
Works great with [BorgBase.com](https://www.borgbase.com) - Simple and Secure Hosting for your Borg Repositories. To manage BorgBase repos via Ansible, also see Andy Hawkins' [BorgBase Collection](https://galaxy.ansible.com/adhawkins/borgbase).
Main features:
- Set up Borg and Borgmatic
- Add cron job at random time
- Provision new remote [BorgBase.com](https://www.borgbase.com) repo for storing backups (optional)
**Main features**
- Install Borg and Borgmatic from PyPi or distro packages
- Set up Borgmatic config
- Schedule regular backups using Cron or Systemd timer
## Breaking changes
- Older versions of this role set up a separate Cron job for creating and checking
backups. With recent Borgmatic version, this feature is now managed in Borgmatic.
As a result the extra Cron job will be removed by this role.
- Older versions of this role only supported Cron for scheduling. If you use
Systemd timers, be sure to remove the Cron job in `/etc/cron.d/borgmatic` first.
The role will also alert you when trying to use both timers.

## Role Variables
### Required Arguments
- `borg_repository`: Full path to repository. Your own server or [BorgBase.com](https://www.borgbase.com) repo. Not required when using auto creation of repositories. Can be a list if you want to backup to multiple repositories.
- `borg_source_directories`: List of local folders to back up.
### Required Variables
- `borg_repository`: Full path to repository. Your own server or [BorgBase.com](https://www.borgbase.com) repo.
Can be a list if you want to backup to multiple repositories.
### Optional Arguments
### Optional Variables
- `borg_dep_packages`: Dependency Packages to install `borg(backup)` and `borgmatic`.
- `borg_distro_packages`: contains the names of distributions packages for `borg(backup)` and `borgmatic`, only used if `borg_install_method` is set to `package`.
- `borg_encryption_passcommand`: The standard output of this command is used to unlock the encryption key.
- `borg_encryption_passphrase`: Password to use for repokey or keyfile. Empty if repo is unencrypted.
- `borg_exclude_from`: Read exclude patterns from one or more separate named files, one pattern per line.
- `borg_exclude_patterns`: Paths or patterns to exclude from backup. See [official documentation](https://borgbackup.readthedocs.io/en/stable/usage/help.html#borg-help-patterns) for more.
- `borg_install_method`: By default `pip` is used to install borgmatic. To install via your distributions package manager set this to `package` and (if needed) overwrite the `borg_distro_packages` variable to contain your distributions package names required to install borgmatic. Note that many distributions ship outdated versions of borgbackup and borgmatic; use at your own risk.
- `borg_require_epel`: When using `borg_install_method: package` on RHEL-based distributions, the EPEL repo is required. To disable the check (e.g. when using a custom mirror instead of the `epel-release` package), set this to `false`. Defaults to `{{ ansible_os_family == 'RedHat' and ansible_distribution != 'Fedora' }}` (i.e. `true` on Enterprise Linux-based distros).
- `borg_lock_wait_time`: Config maximum seconds to wait for acquiring a repository/cache lock. Defaults to 5 seconds.
- `borg_one_file_system`: Don't cross file-system boundaries. Defaults to `true`
- `borg_pip_packages`: Dependancy Packages (pip) to install `borg(backup)` and `borgmatic`.
- `borg_remote_path`: Path to the borg executable on the remote. It will default to `borg`.
- `borg_remote_rate_limit`: Remote network upload rate limit in kiBytes/second.
- `borg_retention_policy`: Retention policy for how many backups to keep in each category (daily, weekly, monthly, etc).
- `borg_ssh_command`: Command to use instead of just "ssh". This can be used to specify ssh options.
- `borg_source_directories`: List of local folders to back up. Default is `/etc/hostname` to prevent an empty backup.
- `borg_ssh_key_name`: Name of the SSH public and pivate key. Default `id_ed25519`
- `borg_ssh_key_file_path`: SSH-key to be used. Default `~/.ssh/{{ borg_ssh_key_name }}`
- `borg_ssh_key_type`: The algorithm used to generate the SSH private key. Choose: `rsa`, `dsa`, `rsa1`, `ecdsa`, `ed25519`. Default: `ed25519`
- `borg_ssh_command`: Command to use instead of just "ssh". This can be used to specify SSH options.
- `borg_version`: Force a specific borg version to be installed
- `borg_venv_path`: Path to store the venv for `borg(backup)` and `borgmatic`
- `borgmatic_check_last`: Number of archives to check. Defaults to `3`
- `borgmatic_checks`: List of consistency checks. Defaults to `['repository']`
- `borgmatic_config_name`: Name to use for the borgmatic config file. Defaults to `config.yaml`

- `borgmatic_checks`: List of consistency checks. Defaults to monthly checks. See [docs](https://torsion.org/borgmatic/docs/how-to/deal-with-very-large-backups/#check-frequency) for all options.
- `borgmatic_config_name`: Name to use for the Borgmatic config file. Defaults to `config.yaml`
- `borgmatic_timer_hour`: Hour when regular create and prune cron/systemd-timer job will run. Defaults to `{{ 6 | random }}`
- `borgmatic_timer_minute`: Minute when regular create and prune cron/systemd-timer job will run. Defaults to `{{ 59 | random }}`
- `borgmatic_hooks`: Hooks to monitor your backups e.g. with [Healthchecks](https://healthchecks.io/). See [official documentation](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/) for more.
- `borgmatic_large_repo`: Less frequent, monthly repo checking. Defaults to `true`
