What is NDMP backup in NetBackup?

What is NDMP backup in NetBackup?

NDMP allows to initiate and control backups and restores of Network Attached Storage (NAS) systems. NDMP architecture follows the client and server model: The NetBackup master or media server where NetBackup for NDMP is installed is called a NetBackup for NDMP server.

What is NDMP storage?

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).

Why was the NDMP formed?

The protocol is called Network Data Management Protocol (NDMP). The objective of the protocol is to help address the problem of backing up networks of heterogeneous file servers, including dedicated file servers (“filers”), with any of several backup applications.

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.

Why is my NDMP backup status 99?

Cause: Status 99 in NDMP backups is generic. Further troubleshooting is required. During regular (standard) NDMP backups, avoid potential NDMP communications failures between NetBackup media servers and the Network Attached Storage (NAS) host.

How to debug the NetBackup backup?

On the NetBackup console, go to Host Properties –> Media Server and double-click the media server that services this backup to open the Properties dialog box. Go to the Logging section and change the global logging level to 5 (maximum). Please make a note of the current logging level before changing it in order to reset it after debugging is done.

How do I check the logs for NDMP backup failures?

For NetBackup 6.0 systems, check the logs for the ndmpagent originator ID for the server that is being created. For NetBackup 6.0 systems, the unified logs for ndmpagent originator id 134 may list the following errors at the time the backup failure occurred. In this example, localhost (127.0.0.1) is being used as the name of the NDMP server.

What is the difference between remote NDMP and local NDMP backup?

Remote NDMP : The backup is performed on the media server, using the device paths defined to the media server. Local : The backup is performed using the device paths attached/zoned to the NAS host. 3-Way : The backup of a NAS host is performed using the device paths attached/zoned to another NAS host 1.
