A Integrating Citrix XenServer
and HP Data Protector

Introduction

This appendix describes a script based solution that, when used together with standard
Data Protector functionality, enables online and offline backup and restore of Virtual
Machines hosted on a Citrix XenServer. For the supported version of Citrix XenServer
for your version of Data Protector, refer to the HP Data Protector A.06.1x Virtualization
support matrix.

Integration concepts

Types of backup

Using this integration, you can perform both online and offline backups. In both
cases, only full backups of virtual machines are available.

Online backup

Online backups are performed without stopping the virtual machines concerned,
using the snapshot functionality available on the Citrix XenServer. By creating a
snapshot of a virtual machine, a copy of the whole virtual machine is created, using
the capabilities of the underlying storage repository and is saved as a template virtual
machine. This template can subsequently be used to restore the disks of the original
virtual machine, or to create new virtual machines as exact copies of the original at
the time of the snapshot.
• online. The user selects which virtual machine, or virtual machines, Data Protector
should back up without disturbing their power state(s).
• allOnline. Data Protector backs up all virtual machines present in the XenServer
without disturbing their power states.
