This script is useful for managing Duplicity backups in a headless environment. The main advantages provided by this wrapper are better log-file handling, easier cron scheduling, and simpler command line execution.
I consider this wrapper to be in Beta until the related ansible role is released.
###Install
####Prerequisites
The following python packages are required:
- duplicity
####Setup
The configuration file default.conf is expected to be in /etc/duplicity/. Settings to change include SERVER, GPG_PASSPHRASE, FTP_PASSWORD
(if you use FTP instead of sftp), and the ssh IdentityFile path in BACKUP_PARAM.
Logging: The script currently expects write access to /var/log/duplicity.log and the folder /var/log/duplicity
for session logs. If you're running as an unprivileged user these log destinations need to be created manually.
###Commands
The main commands are:
dup -b- perform backup (daily, weekly, whenever)dup -u- cleanup archives (monthly, yearly)
Available commands include:
dup - dup[licity] Management Script
Syntax: dup [command] [options]
Commands:
-b perform backup
-h help menu
-l list backup files
-o output todays log
-r restore files (requires: -f -d [-t])
-s status of backup
-u cleanup backup(s)
-x remove backup(s)
See configuration file for parameters used by `-x`
Options:

Unless specified, `/etc/duplicity/default.conf` is used
