The CA ARCserve Backup Agent for Virtual Machines lets you protect VMware-based data that resides on local storage and on a storage area network (SAN). For all data store types, the VMs must be accessible from the backup proxy system.
The list that follows describes the environment configuration requirements for each of the data store types:
■ SAN, iSCSI Data Stores:The backup proxy system must be attached to the same disk where the VM resides and must be attached using the same SAN, iSCSI infrastructure.
■ Local Storage Data Stores: The VMs must reside on disks that are attached directly to the VMware ESX Host system. With local storage environments, the backup proxy system should be able to communicate with the VMware ESX Host system via the LAN.
Note: The terms SAN/iSCSI are used to denote shared storage between Proxy and VMware ESX Host systems. Wherever SAN is mentioned is also applicable to iSCSI environments where Disks are shared using iSCSI infrastructure.
Supported transport modes:
VDDK makes it possible to integrate storage-related applications, including backup, using an API rather than a command-line interface. VMware has developed back-ends that enable efficient access to data stored on ESX/ESXi clusters. Third party developers like CA can access these data paths (called advanced transports) through the virtual disk library. Advanced transports provide the most efficient transport method available, to help maximize application performance.
CA ARCserve supports LAN (NBD), SAN, and HotAdd transport modes using VDDK.
