plone.wabac

plone.wabac ("way-back") is a transitional package providing an add-on for a new kind of "undo" in Plone. It provides a means of logging deletion metadata and restoring items that have been deleted to a previous known state, using a ZODB history, but not ZODB's native undo feature, which has known complications in complex real world scenarios.

It is the hope of this add-on's author that such functionality can be proposed for implementation in a future Plone release (PLIP), and enhanced with additional community contribution.

plone.wabac relies on zc.beforestorage and has the ability to undo to any checkpoint in your (kept) pack history.

Features

Keeps a log of deletion metadata. This metadata can be pruned by user action to remove items earlier than your pack history. However, such history of deletion may be enumerated beyond capacity to restore, if useful as an audit trail.
Can restore content and minimal path dependencies from previous snapshots of your system state (transactions).
Is able to restore both deleted and modified content.
Allows a user with the "Site Administrator" role to restore one or more deleted and/or modified items to previous state, easily with selection.
Application-level restoration does not require or utilize ZODB transactional undo; rather, restoration uses standard content APIs, but makes efforts to preserve original unique identifiers of restored objects.

Documentation

This product is an early proof of concept, and documentation will be forthcoming, in part based on presentation of this functionality at the 2016 Plone Digital Experience Conference.
