Create an inventory file containing your borg hosts
~/borg-inventory:
[borg]
localhost
rpi ansible_ssh_user=pi
...
Create a vault file containing your borg_passphrase
ansible-vault edit ~/borgpassphrase.vault
Prepare your backup jobs:
~/borgjobs.yml
backup_jobs:
- source: /home/user/Documents
archive: /media/data1/borgbackup
Setup borg and the backup jobs:
ansible-playbook -i ~/borg-inventory site.yml \
--ask-vault-pass \
-e@~/borgpassphrase.vault \
-e@~/borgjobs.yml
A resulting job will look like that:
borg list /path/toarchive
20191108_rpi-9-media-data1-Documents Fri, 2019-11-08 11:29:06 [26e0c747a7dadef2eb97c26cc8bc88b8e9ac30e03d5b58c9e2c4ab1f5382a411]
The current date and the source path (/ replaced by -) is appended to the jobname.
Borgbackup is installed by default, using its own in an virtualenv using the python package from pip.
DISCLAIMER: The passphrase is currently part of the resulting crontab entry on the remote host.
