What this formula does

This formula will install the borgbackup package (assuming it is already available on your machine's sources). The clients will periodically (via cron) run a borgbackup.sh which pushes backups to a master. Borg supports backups on local filesystems and remote hosts via ssh. This formula requires ssh keys to be used when connecting to a remote host via ssh.

With the default configuration borg will backup every night, except on sundays where a backup plus a borg check of the last 7 snapshots will be done.

Requirements

• cron
• cronic (will be installed automatically)

Installation

See the full Salt Formulas installation and usage instructions.

Configuration

Carefully read through the default list of included and excluded backup dirs under borg/defaults.yaml.

Configuration is done via pillar. See example.pillar for examples.

States

• borg.backup Installs borgbackup, sets up borgbackup.sh and borgwrapper.sh. Important: Run /root/borgbackup.sh once manually because ssh needs to verify the host and asks you to accept the hostkey.
• borg.master Installs borgbackup, sets up repositories and sets up authorized_keys
