Configuring default settings

1
Start the Backup Job Wizard, and click Create New next to the Selections list. Open the NetVault Backup Server. Select VMware Plugin, and in the Actions list, click Configure.
In the Navigation pane, click Change Settings. On the Configuration page, click Server Settings, and then click Plugin Options.
SAN mode: The SAN transport mode supports virtual machine disks stored on Fibre Channel SAN, iSCSI SAN, or Serial Attached SCSI (SAS) storage devices. This transport mode requires a physical NetVault Backup Client. The SAN mode allows you to completely offload backups to a physical NetVault Backup Client.
To use this transport mode, select san. Verify that the NetVault Backup Client on which the plug‑in is installed has SAN connectivity to the VMFS LUN. On new plug-in installations, the san transport mode is selected by default.
SCSI Hot-Add mode: The SCSI Hot-Add mode supports all types of storage devices. To use this transport mode, the NetVault Backup Client must be installed on a virtual machine. The SCSI Hot-Add mode does not require you to expose SAN LUNs to the NetVault Backup Client. This transport mode is not as efficient as the SAN mode, which does not cause any overhead on the ESX Server host, but it is more efficient than the LAN mode.
LAN mode: The LAN transport mode supports all types of storage devices. You can use the LAN transport mode if the ESX/ESXi Server uses local storage devices or NAS to store its virtual machine disks. This transport mode does not require a physical NetVault Backup Client; you can use this transport mode if the NetVault Backup Client is installed on a virtual machine.
The LAN mode uses the Network Block Device (NBD) protocol to access virtual disks. The ESX Server host reads data from the storage device, and sends the read data across a network channel to the plug-in.
The nbd transport mode performs unencrypted data transfers and can be used if the ESX/ESXi Server and Plug‑in for VMware reside on a secure isolated network. nbd is faster than nbdssl, and takes fewer resources of the ESX Server and NetVault Backup Client.
The nbdssl transport mode performs encrypted data transfers and can be used to protect sensitive data.
Auto mode: To automatically select the most suitable transport mode, select Auto.
Depending on the type of storage your ESX or ESXi Server has access to, select san, hotadd, nbd, or nbdssl. If no alternative is available, select none. On new plug-in installations, the fallback transport mode is set to nbd by default.
Hosts and Clusters: The Hosts and Clusters view is the default inventory view for the Plug‑in for VMware.
This Hosts and Clusters view provides a hierarchical view of the hosts, clusters, and their child objects. In a cluster setup managed by a vCenter Server, the virtual machines are displayed under the Cluster node. In a standalone ESX Server setup, the virtual machines are displayed under the individual hosts.
The Hosts and Clusters view does not display the folders created on the vCenter Server.
VMs and Templates: The VMs and Templates view provides a flat view of all virtual machines and templates in the inventory; the virtual machines are grouped by Datacenters and folders.
NOTE: To switch between the two views, select the ESX/ESXi or vCenter Server on the NetVault Backup Selections page, and in the Actions list, click Toggle Inventory View. This option is only available when the server node is open.
This setting determines the interval at which the plug-in updates progress statistics in the Job Monitor window. The default value for this option is 10 seconds. To change the default interval for progress updates, type or select a new value. The progress interval is specified in number of seconds.
The default path for the Working Directory is <NetVault Backup home>\tmp on Windows and <NetVault Backup home>/tmp on Linux. To change the location, specify the full path. If you specify a path that does not exist, the plug-in automatically creates it on the NetVault Backup Client.

Configuring CBT

Enabling CBT on a virtual machine

*NOTE: You can also use the backup option “Enable Changed Block Tracking for VM” to automatically enable tracking on all virtual machines that are included in a backup job. For more information about this option, see Other backup options for Plug‑in for VMware.
