PHD Virtual Technologies has released version 3.6 of esXpress application, to support VMware vSphere 4. The new version 3.6 also includes enhancements for all versions of VMware’s ESX platform version 3.0.2 and above. The deduplication engine increases backup speeds for file-level restores, as well as VMDK restores and data archival through a Windows Share.

PHD Virtual said that the new version 3.6, with support for vSphere 4, performs backup and recovery using virtual environment. By creating virtual backup appliances (VBAs), small virtual machines, the new version can be deployed on VMware servers, and allow back up of virtual machines.

The company said that the new performance enhancements include: file level restore speeds, data restoration and archival through Windows’ Shares, PHDD deduplication image-level, and accelerated deduplication engine to provide initial backups.

In addition, esXpress continues to support up to 16 concurrent backup/restore streams per host and all backups can be self-restored without using esXpress or other virtual machine infrastructure, PHD Virtual said.

Joe Julian, executive chairman of PHD Virtual, said: Along with now supporting VMware vSphere 4, we continue to enhance esXpress’ performance so that all customers can benefit from these performance improvements in any VMware environment, 3.0.2 and above.

The new version esXpress 3.6 supporting VMware vSphere 4 is available in small business and enterprise version starting at $1,000 per host with unlimited number of sockets.
