XenServer CBT sample code

This repository contains a collection of scripts that use the XenServer changed block tracking API.

These scripts are an example of how to use the changed block tracking feature from end-to-end including:

• enabling changed block tracking
• copying changed blocks
• destroying unnecessary snapshot data.
• coalescing incremental backup onto base VDI
• importing backup VDI

The examples are written in Python.
