Overview

borgmatic is a simple Python wrapper script for the Borg backup software that initiates a backup, prunes any old backups according to a retention policy, and validates backups for consistency. The script supports specifying your settings in a declarative configuration file rather than having to put them all on the command-line, and handles common errors.

Here's an example config file:

location:
    # List of source directories to backup. Globs are expanded.
    source_directories:
        - /home
        - /etc
        - /var/log/syslog*

    # Paths to local or remote repositories.
    repositories:
        - user@backupserver:sourcehostname.borg

    # Any paths matching these patterns are excluded from backups.
    exclude_patterns:
        - /home/*/.cache

retention:
    # Retention policy for how many backups to keep in each category.
    keep_daily: 7
    keep_weekly: 4
    keep_monthly: 6

consistency:
    # List of consistency checks to run: "repository", "archives", or both.
    checks:
        - repository
        - archives

borgmatic is hosted at https://torsion.org/borgmatic with source code available. It's also mirrored on GitHub for convenience.
