Enhanced Block-Level Data Analysis for the Agent for Virtual Machines

This release of the CA ARCserve Backup Agent for Virtual Machines includes the following:

• The Agent for Virtual Machines now includes enhanced block-level data analysis for backing up data that resides on Hyper-V and VMware virtual machines. The agent now identifies the used blocks of data on virtual disks, and backs up only the used blocks of data. This capability lets CA ARCserve Backup decrease the overall backup time for jobs.
• The Agent for Virtual Machines now backs up virtual machines that are configured with virtual compatibility mode raw device mappings (RDMs).

  Note: VMware does not support restoring virtual compatibility mode RDMs as RDMs.Therefore, CA ARCserve Backup restores the virtual compatibility mode RDMs as virtual hard disks on your datastore.

• The Agent for Virtual Machines now uses vStorage APIs for Data Protection (VADP). VADP lets CA ARCserve Backup perform centralized virtual machine backups without the disruption and overhead of running backup tasks from inside each virtual machine.
• The Agent for Virtual Machines now deploys VMware Virtual Disk Development Kit (VDDK) 1.2.1 on all systems where you install the agent. You no longer must download and install VDDK on your backup proxy systems.
