[Duplicity-talk] mbkp: A new, modular Duplicity front end

[Elifarley Callado Coelho Cruz]

I decided to share a tool I've started developing in late 2010, named 'mbkp'.

Source code, wiki, issues and planned features:
http://bitbucket.org/elifarley/mbkp/

(I have yet to improve the information provided in the wiki)

------------


About:
mbkp is a modular backup tool in 2 senses: it groups common backup
configuration in named modules, and its source code departs from the
monolithic style by grouping similar functions in separate modules.

Goals:
Simplify backup management
Leverage similarities between source version control and backup (mbkp
status / mbkp log are similar to hg status / hg log or svn status /
svn log, for instance)
Source code should use best practices in shell / Bash scripting and be
easy to extend.

Main Features:
Backup configurations are stored in modules
Easily create, export and import configuration modules
Built-in help
Concurrent backups of a module are detected and skipped
Simple backup of MySQL databases
List of DB tables to skip
List of files to include and exclude is relative to the source (no
need to repeat the source prefix for every line)
Various pre- and post-hooks
Compatible with older and current versions of Duplicity

Examples:


$ mbkp
