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.
It's possible to configure append-only repositories to secure the backups against deletion from the client.
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.
[borgbackup_servers]
backup1.fiaas.co
[borgbackup_management]
supersecurehost
Define group- or hostvars for your backup endpoints and retention:
borgbackup_servers:
- fqdn: backup1.fiaas.co
user: borgbackup
type: normal
home: /backup/
pool: repos
options: ""
- fqdn: yourhost.rsync.net
user: userid
type: rsync.net
home: ""
pool: repos
options: "--remote-path=borg1"
borgbackup_retention:
hourly: 12
daily: 7
weekly: 4
monthly: 6
yearly: 1
WARNING: the trailing / in item.home is required.
Define a borg_passphrase for every host. host_vars\client1:
borgbackup_passphrase: Ahl9EiNohr5koosh1Wohs3Shoo3ooZ6p
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_cron_day: "*"
borgbackup_cron_hour: "{{ 59|random }}"
borgbackup_cron_minute: "{{ 5|random }}"
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.
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.
Usage
Configure Borg on the server and on a client:
ansible-playbook -i inventory/test backup.yml -l backup1.fiaas.co
ansible-playbook -i inventory/test backup.yml -l client1.fiaas.co
