Integrating Citrix XenServer and HP Data Protector

This means that the virtual machine can be restored successfully, but it is only possible to restore

the disks to a single storage repository, regardless of the original configuration.

Main integration components

To function, this integration requires the following components:

• Supported Citrix XenServer

• HP Data Protector client(s) with:

– Disk Agent

– Media Agent

• Integration scripts

A simple example layout for these components (with both Disk Agent and Media Agent on the

same Data Protector client) is shown in

Figure 2.

No scripts are installed on the Citrix XenServer, but its export facility is used by the integration

scripts. The integration scripts themselves are all installed on the Data Protector client with the Disk

Agent installed.

During backup, virtual machines, or virtual machine disks, are exported to the Disk Agent host

and backed up using Data Protector. The device used for the backup can be any device

supported by Data Protector for file-system backup.

Installation of the integration

This section gives detailed instructions for the installation of the XenServer integration.

Prerequisites

The machine on which the integration is to be installed must be a Data Protector client (shown as

DP Client in

Figure 2) with the Data Protector Disk Agent installed, and must be a member of a

Data Protector Cell. For further details, see the

HP Data Protector installation and licensing guide.

The Data Protector Disk Agent must be installed first, since other software must be installed in

specific Data Protector directories.

The following software must then be installed on the Disk Agent host:

• Python version 2.5.x or 2.6.x (available from

http://www.python.org/download). This must be

installed first. (Also, see the note regarding Pycurl below).

Install the software in the following directories:

– On Windows:

Data_Protector_home\bin

– On Linux:

/opt/omni/bin
