Baku

Baku is a minimal sftp backup manager that can be configured to perform multiple backups of different files across many hosts.

Installation

An installation script is provided in order to setup a Raspberry pi as a minimal backup server.

chmod +x setup.sh
./setup.sh

If you have Python already installed on your system, the only requirements needed is the library pysftp, which can be installed with pip.

pip3 install pysftp

Configuration

The config.py file stores the configuration of the different backup files and hosts. This file can be easily created by copying the config.dist.py file.

DESTINATION_FOLDER = ''                     # Destination path to store the files
DEFAULT_DAILY_LIMIT = 14                    # Default daily backups to store
DEFAULT_WEEKLY_LIMIT = 6                    # Default weekly backups to store
DEFAULT_MONTHLY_LIMIT = 12                  # Default of monthly backups to store


hosts = {
    'HOSTNAME-A': {
        'ip': 'X.X.X.X',
        'username': 'BACKUP_USERNAME',
        'private_key': '/path/to/file',
        'private_key_pass': 'PRIVATE_KEY_PASSWORD',
    },
}


backups = [
    {
        'name': 'Name of this backup',
        'hostname': 'HOSTNAME',             # Hostname key from hosts configuration
        'location': '/your/host/file',      # Source path of the file
        'destination': 'my_backup/',        # Destination path inside the DESTINATION_FOLDER
        'daily_limit': '14',                # Custom daily backups to store
        'weekly_limit': '',                 # Custom weekly backups to store
    }
