Overview
atticmatic is a simple Python wrapper script for the Attic backup software that initiates a backup and prunes any old backups according to a retention policy. 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]
# Space-separated list of source directories to backup.
source_directories: /home /etc
# Path to local or remote Attic repository.
repository: user@backupserver:sourcehostname.attic
[retention]
# Retention policy for how many backups to keep in each category.
keep_daily: 7
keep_weekly: 4
keep_monthly: 6
Additionally, exclude patterns can be specified in a separate excludes config file, one pattern per line.

atticmatic is hosted at http://torsion.org/hg/atticmatic/ and is mirrored on GitHub and BitBucket for convenience.
Setup
To get up and running with Attic, follow the Attic Quick Start guide at https://attic-backup.org/quickstart.html to create an Attic repository on a local or remote host.
If the repository is on a remote host, make sure that your local root user has key-based ssh access to the desired user account on the remote host.
To install atticmatic, run the following from the directory containing this README:
python setup.py install
Then copy the following configuration files:
sudo cp sample/atticmatic.cron /etc/cron.d/atticmatic
sudo mkdir /etc/atticmatic/
sudo cp sample/config sample/excludes /etc/atticmatic/
Lastly, modify those files with your desired configuration.
Usage
You can run atticmatic and start a backup simply by invoking it without arguments:
atticmatic
This will also prune any old backups as per the configured retention policy. By default, the backup will proceed silently except in the case of errors. But if you'd like to to get additional information about the progress of the backup as it proceeds, use the verbose option instead:
atticmattic --verbose
If you'd like to see the available command-line arguments, view the help:
atticmattic --help
Running tests
To install test-specific dependencies, first run:
python setup.py test
To actually run tests, run:
nosetests --detailed-errors
