What is NDMP in NetBackup?
NetBackup for NDMP is an optional NetBackup application. It enables NetBackup to use the Network Data Management Protocol (NDMP) to initiate and control backups and restores of Network Attached Storage (NAS) systems.
How does NetApp NDMP work?
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.
How do I connect to my NDMP server?
At the NDMP Server step of the wizard, enter the name of the NDMP server and connection details. In the NDMP server name and port field, enter the name or the IP address of the NDMP server you want to connect and the port for the connection. Check your NAS device settings for details.
What is NDMP backup in Backup Exec?
NDMP is an Internet-Draft standard that uses port 10000 by default. The Veritas Backup Exec NDMP Option lets Backup Exec use the Network Data Management Protocol (NDMP) to initialize and control backups and restores of Network Attached Storage (NAS) devices such as NetApp filers as explained below.
What is Ndmp port number?
TCP 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 does NDMP stand for?
Network Data Management Protocol
Network Data Management Protocol (NDMP) is an open protocol to control data backup and recovery communications between primary and secondary storage in a heterogeneous network environment. Simply put, the protocol is meant for network-based backup for network-attached storage (NAS).
What is NDMP port number?
What is NDMP server?
Network Data Management Protocol (NDMP) is an open protocol to control data backup and recovery communications between primary and secondary storage in a heterogeneous network environment. Simply put, the protocol is meant for network-based backup for network-attached storage (NAS).
What is NDMP copy?
The Network Data Management Protocol (NDMP) is a standardized protocol for controlling backup, recovery, and other types of data transfer between primary and secondary storage devices, such as storage systems and tape libraries.
What is NetWorker ports range?
A NetWorker host can allocate any port in the defined service port range and the NetWorker daemons select the dynamic ports within that range randomly. The default range is 7937-9936.
Who invented NDMP?
The History of NDMP Version one of NDMP was invented and developed in 1995 by NAS pioneer NetApp and PDC who collaborated to solve an issue that was increasingly challenging NAS users and the inability to reliably protect their data.
What is NDMP use?
Why was the NDMP formed?
NDMP separates the control path from the data path, which reduces the demand on network resources and allows you to implement local backups and leverage remote systems for disaster recovery. NDMP also creates a standard way for file servers in heterogeneous networks to communicate with network-attached tape devices.

What is Nsrexecd?
nsrexecd is used by NetWorker servers to perform automatic operations on NetWorker clients. It is currently used by savegrp(1) to start saves, pre-migrations and storage node functions on NetWorker client machines.
What is NDMP service?
How do I restart Nsrexecd?
Root user can restart rpcbind with the command “/etc/init. d/rpcbind restart”, or by restarting the host machine. At this point nsrexecd will be running correctly. Use ‘ps -ef | grep nsr’ to check for the nsrexecd process, or try the command “ism_catalog -create_bootstrap” to confirm functionality.
What is NetWorker Remote Exec service?
Synopsis. Stack-based buffer overflow in the NetWorker Remote Exec Service (nsrexecd.exe) in EMC Software NetWorker 7. x.x allows remote attackers to execute arbitrary code via a (1) poll or (2) kill request with a “long invalid subcmd.”
What is 3 way NDMP?
The NDMP three-way backup is also known as the remote NDMP backup. During a three-way NDMP backup operation, a data management application (DMA) on a backup server instructs the cluster to start backing up data to a tape media server that is either attached to the LAN or directly attached to the DMA.
How do I integrate NDMP backups into NetBackup’s scheduling?
It is possible to integrate NDMP backups into NetBackup’s scheduling with the use of the NetBackup’s NDMP agent. This enables a NetBackup media or master server to send NDMP control commands to a compatible filer and for the filer to send the data to the appropriate backup target.
What are the different types of backup for NetBackup?
Backups can be conducted in any of the following ways: 1 NDMP local backup#N#See NDMP local backup. 2 NDMP three-way backup#N#See NDMP three-way backup . 3 Backup to a Media Manager storage unit on the NetBackup server#N#See Backup to Media Manager storage units (remote NDMP). More
What is port 10000 in NetBackup?
Port 10000 is the port the NDMP service listens on and it is this port to which NetBackup will be sending the NDMP operations, hence connectivity to it is reuqired. A simply telnet test to this port on the filer will confirm that the port is contactable
