PHD Virtual Backup for Citrix XenServer

Friday, 07 May 2010 10:24

First Citrix Ready Solution for Virtual Backup and Recovery

PHD Virtual Backup for Citrix XenServer is the first backup and recovery solution purpose built for virtualized environments to be certified in the Citrix Ready program.  Using PHD Virtual Backup for Citrix XenServer/XenDesktop, customers will enjoy the benefits of

The fastest and most cost effective backup that minimizes storage requirements

The most reliable solution for data integrity with source side deduplication and enhanced self healing backups

And since PHD Virtual’s products will support both XenServer and XenDesktop, customers can leverage the same solution across their virtual environment.


Because PHD is built for use with virtual platforms, it uses virtual appliances and doesn’t compromise hypervisor performance. PHD Virtual Backup is cost effective because there is no additional hardware to deploy or additional software licenses required.

Backups are controlled from within XenCenter, giving end users a highly desired single pane of glass control of their infrastructure.  The PHD Dashboard contains status info about backups. Multiple PHD vApps can be deployed in a Citrix XenServer Resource Pool. 

PHD Dedupe is our patent pending technology which creates pointers to blocks of data used by multiple backups. Compression can be enabled or disabled (such as when used with hardware dedupe storage) PHD’s approach to backup features source-side deduplication and compression which reduces network and target storage requirements.


Change Block Tracking (CBT)

also called Differential Snapshot Tracking will be supported – this significantly reduces backup time by skipping unchanged blocks.  The result reduces the load on the SAN delivering backup data to our vApp.  Where CBT is not available, PHD Virtual Backup will parse all blocks to determine what has changed – this flexible approach uses more SAN I/O but will then deliver reduced I/O to backup storage target preserving the storage benefit.



of data backup is an area that PHD introduced several years ago and this functionality is present in PHD Virtual Backup for Citrix XenServer.  In fact, administrators will be able to choose from several modes: Quick V for new data blocks, Full V used before backup and Backup V to scan random blocks after backup.


Parallel Backups

provides the ability to process multiple VMs with multiple virtual disks in parallel processing/multi-threading.  The initial release supports 4 simultaneous backup streams per vApp.


With mission-critical applications moving to the virtual environment, more stringent business continuity concerns come into play. 

For Restoration: PHD Virtual Backup provides assistance whether the restoration is a mistakenly deleted file or the complete loss of a data center facility. The administrator can choose from the following options:

File Level Restoration (FLR) – A key feature that differentiates PHD Virtual from other solutions, FLR allows administrators to extract single or multiple file(s) from block level backup.

Application Level Restoration (ALR) – this level of restoration is not offered in most image level backup products; PHD Virtual will offer it for select applications including Microsoft Exchange which will allow ability to export a mailbox or single email from the block level backup.

VM Level Restoration (VMLR) – enables the restoration of either single disk or complete VM from backup helping administrators to restore an environment from complete loss quickly and efficiently. The vApp will connect to a new virtual disk and restore data to this location – passing from one VM to another – with minimal use of XenServer DOM0 interface.

Export Share – this is the interface to take PHD Virtual Backup data from disk to tape in XenServer native format. It utilizes Date Smart Dynamic Export (DSDE) which allows you to select VMs for export to tape based on when backups were completed and by VM name.
