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:

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

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

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

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

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

borgmatic is hosted at with source code available. It's also mirrored on GitHub for convenience.
