How does NDMP backup work?
With NDMP, heterogeneous network file servers can communicate directly to a network-attached tape device for backup or recovery operations. Without NDMP, administrators must remotely mount NAS volumes on their server and back up or restore the files to directly attached tape library devices.
What is NDMP backup NetApp?
1 NDMP Backups The Network Data Management Protocol (NDMP) developed by NetApp is used for controlling backup services to network-attached storage (NAS) devices. NDMP allows data to be transferred between storage devices and backup targets and reduces the load on the backup server.
What is NDMP backup in commvault?
Commvault NDMP support Basic NDMP functionality provides for local (LAN-Free) backup and restore to an attached tape device. NDMP backups can also be written to a tape device attached to another NDMP host.
What is NDMP backup in NetBackup?
NDMP allows to initiate and control backups and restores of Network Attached Storage (NAS) systems. The NetBackup master or media server where NetBackup for NDMP is installed is called a NetBackup for NDMP server. The host where the NDMP server application resides is called an NDMP host.
What is a function of the NDMP server in an NDMP based backup approach?
Network Data Management Protocol (NDMP) is a protocol used to manage backup and restore operations on a Network Attached Storage (NAS) device. NDMP uses a client server model, where the Data Protector NDMP Media Agent client controls the backup, while the NDMP Server performs the actual backup operations.
What is NDMP port number?
port 10000
Network Data Management Protocol (NDMP) runs on TCP port 10000 and is used primarily for backup of network-attached storage (NAS) devices, such as storage systems.
What is Ndmp port number?
What is Ndmp copy?
NDMP, and its use of dump and restore, can be used to copy data between different locations within, or between, storage systems. These storage systems can run different releases and/or operate in different modes of Data ONTAP. NetApp, and others, provide several utilities to facilitate copying of data using NDMP.
What is iDA in commvault?
Commvault iDA helps to ensure that critical business data is captured and stored in an app-consistent format. More importantly, Commvault iDAs can provide granular recovery, such as transactional log-based recovery.
How do I set up an NDMP backup?
Configuring NDMP backup to Media Manager storage units
- Under Media and Device Management > Credentials, click NDMP Hosts. From the Actions menu, choose New > New NDMP Host to display the Add NDMP Host dialog.
- Fill in the values.
- Repeat these steps for each NDMP host that the NetBackup server backs up.
What is NDMP service?
NDMP (Network Data Management Protocol) is an open protocol used to control data backup and recovery communications between primary and secondary storage in a heterogeneous network environment. NDMP addresses a problem caused by the particular nature of network-attached storage devices.
What accurately describes an NDMP based backup in a NAS environment?
NDMP allows a NAS device to send data directly to your home backup servers across the network without the need for backup client intervention. In this way the backup server communicates directly with the NAS appliance, indicating which storage device data can be sent to for backup.
