# Borg backup role
|
||||
This role installs Borg backup on borgbackup\_servers and clients. The role contains a wrapper-script 'borg-backup' to ease the usage on the client. Supported options include borg-backup info | init | list | backup | mount. Automysqlbackup will run as pre-backup command if it's installed.
|
||||
The role supports both self hosted and rsync.net as Borg server.
|
||||
The role supports both self hosted and offsite backup-storage such as rsync.net and hetzner storage box as Borg server.
|
||||
|
||||
It's possible to configure append-only repositories to secure the backups against deletion from the client.
|
||||
|
||||
Ansible 2.4 or higher is required to run this role.
|
||||
|
||||
## Required variables
|
||||
Define a group borgbackup\_servers in your inventory with one or multiple hosts. The group borgbackup\_management is only necessary if you want to enable append-only mode and prune the backups from a secured hosts.

||||

Per default the role creates a cronjob in /etc/cron.d/borg-backup running as root every day on a random hour between 0 and 5am on a random minute. Override the defaults if necessary:
|
||||
```
|
||||
borgbackup_cron_user: root
|
||||
borgbackup_client_user: root
|
||||
borgbackup_cron_day: "*"
|
||||
borgbackup_cron_minute: "{{ 59|random }}"
|
||||
borgbackup_cron_hour: "{{ 5|random }}"
|
||||
```
|
||||
Override borgbackup\_client\_user where required, for example if you have a laptop with an encrypted homedir you'll have to run the backup as the user of that homedir.
|
||||
|
||||
Set borgbackup\_appendonly: True in host or group vars if you want append-only repositories. In that case it's possible to define a hostname in borgbackup\_management\_station where a borg prune script will be configured.
|
||||
Set borgbackup\_appendonly: True in host or group vars if you want append-only repositories. In that case it's possible to define a hostname in borgbackup\_management\_station where a borg prune script will be configured. Only the management station will have permission to prune old backups for (all) clients. This will generate serve with --append-only ssh key options.
|
||||
If you set borgbackup\_appendonly\_repoconfig to True, this will also disable the possibility to remove backups from the management station. (Or at least: it's not possible to remove them till you reconfigure the repository and this is currently not supported in the prune script)
|
||||
Be aware of the limitations of append-only mode: [pruned backups appear to be removed, but are only removed in the transaction log till something writes in normal mode to the repository](https://github.com/borgbackup/borg/issues/3504))
|
||||
|
||||
*Make sure to check the configured defaults for this role, which contains the list of default locations being backed up in backup_include.* Override this in your inventory where required.
