Ansible Role: BorgBackup Client

Set up encrypted, compressed and deduplicated backups using BorgBackup and Borgmatic. Currently supports Debian/Ubuntu, CentOS/Red Hat/Fedora, Archlinux and Manjaro.

Works great with BorgBase.com - Simple and Secure Hosting for your Borg Repositories. To manage BorgBase repos via Ansible, also see Andy Hawkins' BorgBase Collection.

Main features:

• Set up Borg and Borgmatic
• Add cron job at random time
• Provision new remote BorgBase.com repo for storing backups (optional)
