WD Arkeia provides specialized agents for both Microsoft Hyper-V and VMware vSphere/ESX, based on applications programming interfaces (APIs) provided by these two vendors. Our agents perform image backups of one or more virtual machines using just a single backup agent. All backups are done while virtual machines are live and running.
WD Arkeia supports image backups via command line for virtualization environments from Citrix and Parallels. Because RHEV does not yet provide a facility for image backups, we protect RHEV deployments with agents in each guest OS. Learn more about Arkeia solutions for virtual environments.

WD Arkeia's Backup Agent for VMware vSphere takes advantage of VMware's VADP (vStorage APIs for Data Protection). The vStorage API enables backups that previously were not possible with VMware Consolidated Backup (VCB) or console-based backups. The vStorage Backup Agent enables proxy-less backups of VMware virtual machines that can leverage existing LAN or SAN infrastructure. WD Arkeia's backup agent for vStorage performs block-level incremental backups (via Changed Block Tracking) of virtual machines, as well as file-grain restores from image backups. Learn more about WD Arkeia's vStorage Backup Agent.
The Hyper-V Backup Agent leverages Microsoft's Volume Shadow Copy Service (VSS) to perform snapshot-based backups of virtual machines. Both Linux and Windows guest operating systems are supported. For any VSS-aware applications that are running within the virtual machine, for example SQL Server or Exchange, the Hyper-V Backup Agent will perform VSS quiescing of those applications as well. WD Arkeia's source-side deduplication offers all the compression benefits of incremental backups because the Arkeia Backup Agent will only send new (i.e. unknown) blocks over the network to the Arkeia Backup Server.

WD Arkeia is able to perform image backups of Citrix XenServer and other Xen virtualization deployments. The Xen server can be included in an Arkeia backup infrastructure and be fully and automatically protected. Learn more about Arkeia Backup Solutions for XenServer and Xen.
Because RHEV does not currently provide for image backups of virtual machines, WD recommends installing backup agents in each guest OS. WD Arkeia and Red Hat have jointly certified this backup solution. Learn more about WD Arkeia Backup Solutions for RHEV.
Three capabilities make WD Arkeia solutions outstanding for protecting virtualized environments. No other data protection integrates all of these capabilities:
