What is hot add transport mode?

What is hot add transport mode?

HotAdd Transport. 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.

What is NBD transport mode?

Network Block Device (NBD) transport mode, also referred to as LAN transport mode, uses the Network File Copy (NFC) protocol to communicate. Various VDDK and VCB operations use one connection for each virtual disk that it accesses on each ESX/ESXi Server host when using NBD.

What is NBD in VMware?

NBD is a Linux-style kernel module that treats storage on a remote host as a block device. NBDSSL is the VMware variant that uses SSL to encrypt all data passed over the TCP connection.

What are transport modes in VMware?

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.

What is NBD in backup?

NBD (network block device) is the most universal of the VDDK transport modes. It does not require dedicated backup proxy VMs like HotAdd, and works on all datastore types, not just SAN. Sections below give tips for improving NFC (network file copy) performance for NBD backups.

Which of the transport modes are available in Veeam?

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.

What is VMware backup proxy?

VCB proxy (VMware Consolidated Backup proxy) is the server that collects virtual machine (VM) backup data from VMware Consolidated Backup (VCB). VCB, a component of VMware Virtual Infrastructure 3 (VI3) and vSphere 4, takes virtual machine snapshots and mounts them to the centralized VCB proxy server in read-only mode.

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 Veeam NBD?

In regards to transport modes, there are four choices in a Veeam VMware Backup Proxy: Automatic. Direct storage access. Virtual appliance (Hot Add) Network (NBD)

What is guest interaction proxy?

The guest interaction proxy is a backup infrastructure component that sits between the backup server and processed VM. This component is needed if the backup or replication jobs perform the following processing of VMs: Application-aware processing. Guest file system indexing. Transaction logs processing.

What does a backup proxy do?

A backup proxy is an architecture component that sits between the backup server and other components of the backup infrastructure. While the backup server administers tasks, the proxy processes jobs and delivers backup traffic.

How many Veeam proxies do I need?

For virtual proxy servers, it is recommended to configure multiple proxies with maximum 8 vCPUs to avoid co-stop scheduling issues. 5 virtual proxy servers are required in this example.

What is application aware processing?

Application-aware processing is Veeam’s proprietary technology based on Microsoft VSS. Microsoft VSS is responsible for quiescing applications and creating a consistent view of application data on the OS of the Veeam Agent computer.

What is Veeam VIX?

Veeam Backup & Replication uses the VIX API as a network-less connection method to perform Guest Processing when a VM cannot be contacted directly via RPC.

What is Veeam proxy used for?

Veeam proxy sits between the data source and target and is used to process jobs and deliver backup traffic. It allows to offload the Veeam Backup Server and have better performance resulting shorter backup window.

What is Veeam Backup transport?

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.

What is SureBackup?

SureBackup is the Veeam technology that allows you to test VM backups and check if you can recover data from them. You can verify any restore point of a backed-up VM.

What is vmware VIX?

The VIX API (also known as “Vix”) is an API that lets users write scripts and programs to manipulate virtual machines. It is high-level, easy to use, and practical for both script developers and application programmers.

What is VSS in Veeam?

With the Enable VSS integration option selected, Veeam Backup & Replication 4.0 utilizes the Windows Volume Shadow Copy Service (VSS) that ensures consistent backup of VSS-aware application running within your virtual machines (domain controllers, databases and other applications) without shutting them down.
