##Driver

Customers often request “versioning” or “restore/undo” functionality, as a means of data recovery from user error (as opposed to recovery from hardware failure or data loss errors, at which Riak already excels). If an object is changed or deleted by the end user, but later needs to be restored, is there a way to either look at a transaction log to undo the damage, or to explicitly restore the object to a previous version?

##Overview

This solution provides one simple example of an implementation for a transaction/audit journal and restoring lost/deleted objects for a known key. A separate global transaction/audit journal could also be built to provide an index to get an object key in the case where you don't know it beforehand, but that use case is outside the scope of this document.

The algorithm used here depends only on Riak's key/value functionality for two reasons. First, to show that a solution to the problem can be simply and efficiently implemented with a key/value pattern. Second, relyin
