Offline Backup; Disaster Recovery; Backup Processes; Online Backup - HP Data Protector A.06.11 Integration Manual

NOTE:
The types of storage repositories for which online backup is supported is dependent on
the version of XenServer that you are using. Refer to
Online backup is available for Virtual Hard Disk (VHD), Netapp and EqualLogic
storage repositories.

Offline backup

Offline backups are performed after first shutting down the virtual machines concerned.
The complete virtual machine is then saved as an .xva file using the Citrix export
functionality. This file can subsequently be imported into any XenServer to create a
new machine equivalent to the one exported.
• offline. The user selects which virtual machine, or virtual machines, should be
suspended and backed up.
• allOffline. All the virtual machines present in the XenServer are sequentially
suspended and backed up.

Disaster recovery

For disaster recovery, you need a backup of the disks that a virtual machine uses
plus the metadata for the virtual machine. With this integration, this is only possible
with offline backup.

Backup processes

Online backup

The process used by the integration script for an online backup is as follows:
1. Check that snapshot operation is allowed for all the disks of the virtual machine.
2. Snapshot the virtual machine.
3. Export the snapshot to the temporary backup folder as an .xva file.
4. Delete the snapshot.
After the script has finished, the contents of the temporary backup folder are backed
up to the backup device using standard Data Protector functionality.
