In the Virtual appliance mode, Veeam Backup & Replication uses the VMware SCSI HotAdd capability that allows attaching devices to a VM while the VM is running. During backup, replication or restore disks of the processed VM are attached to the backup proxy.

How do you manually test HotAdd functionality?

How to Test

1. Edit the Veeam Proxy that will be processing the VM from Step 1.
2. Click [ Add New Device ]
3. Chose “Existing Hard Disk”
4. Navigate to the location of the base disk from the VM in step 1.
5. After selecting the disk, expand the disk node.
6. Under “Disk Mode” select to “Independent – Nonpersistent”
7. Click [ Ok ]

How do you change transport mode in Veeam?

If several transport modes are available for the same backup proxy, Veeam Backup & Replication will choose the mode in the following order: Direct storage access > Virtual appliance > Network. The selected transport mode is used for data retrieval.

What is VMware HotAdd?

HotAdd is a VMware feature where devices can be added “hot” while a virtual machine is running. Besides SCSI disk, virtual machines can add additional CPUs and memory capacity. HotAdd is a good way to get virtual disk data from a virtual machine to a backup appliance (or backup proxy) for sending to the media server.

What is vProxy appliance?

NetWorker supports vSAN datastore for its virtual appliance known as vProxy, it supports running image backups and restores virtual machines running on vSAN datastores.

Where is Veeam configuration backup stored?

\VeeamConfigBackup\%BackupServer% folder
By default, Veeam Backup & Replication is configured to create a daily configuration backup. The resulting configuration backup file is stored in the \VeeamConfigBackup\%BackupServer% folder on the default backup repository.

What is the name of development kit Veeam uses to work with virtual disks?

VDDK
Like any backup vendor using VMware vStorage API for Data Protection (VADP), Backup & Replication is using the VMware Virtual Disk Development Kit (VDDK) within the Veeam Transport Service.

What is NBD mode Veeam?

In this mode, data is retrieved through the ESXi host over LAN using the Network Block Device protocol (NBD). The Network mode has low data transfer speed over LAN. To take the load off the LAN, Veeam Backup & Replication provides two alternative modes: Direct Storage Access and Virtual Appliance.

What is Veeam transport service?

Veeam Data Mover performs data processing tasks on behalf of Veeam Backup & Replication, such as retrieving source machine data, performing data deduplication and compression, and storing backed-up data on the target storage.

Which are VMware transport modes?

A VMware Backup Host can access Virtual Machine data from datastores using four different methods – SAN, LAN(NBD), HotAdd, NBDSSL. These methods are referred to as VMware Transport modes.

How do I enable hotplug on virtual machine?

How to enable Hot-add/Hot-plug using the vSphere Client:

1. shut down the virtual machine.
2. login to your vSphere Client.
3. select the virtual machine.
4. Edit Settings.
5. change to the “Options-Tab”
6. select Memory/CPU Hotplug.
7. Enable memory hot add and/or CPU Hot Plug.

What is the Veeam vStorage API?

Veeam Backup & Replication leverages VMware vStorage APIs for Data Protection (VADP) for all transport modes except for backup from storage snapshots, the direct NFS transport mode and the virtual appliance transport mode. VADP can be used for VMware vSphere starting from version 4.

How does Veeam Backup & Replication choose the transport mode for backup proxy?

If several transport modes are available for the same backup proxy, Veeam Backup & Replication will choose the mode in the following order: Direct storage access > Virtual appliance > Network. The selected transport mode is used for data retrieval.

What is the difference between network mode and virtual appliance mode?

User Guide for VMware vSphere. The Virtual appliance mode is not so efficient as the Direct storage access mode but provides better performance than the Network mode. The Virtual appliance mode is recommended if the role of a backup proxy is assigned to a VM.

Does hothotadd work with Veeam datastore?

HotAdd is a SCSI feature and does not work for IDE disks. VMware Tools must be installed and up-to-date on the Veeam server and any Veeam proxies. Datastore needs sufficient space for a VM snapshot. Backup and restore of SATA disks in the Virtual appliance mode is supported if you use VMware vSphere 6.0 and later.
