Managing NDMP environment variables

In OneFS, you can manage NDMP backup and recovery operations by specifying default NDMP environment variables. You can also override default NDMP environment variables through your data management application (DMA).

You can add, view, edit, and delete environment variables. The environment variables can be managed on a per-backup-path basis. They are appended to the environment variables passed from a DMA in a backup or recovery session.

The following table lists the DMAs that allow you to directly set environment variables:

Table 1. DMA support for environment variable setting
DMA	Supported directly on the DMA	Supported through OneFS command-line interface
Generic	Yes	Yes
Bakbone	No	Yes
CommVault	No	Yes
Dell EMC	No	Yes
Symantec	No	Yes
Tivoli	No	Yes
Symantec NetBackup	Yes	Yes
Symantec Backup Exec	No	Yes

In case you cannot set an environment variable directly on a DMA for your NDMP backup or recovery operation, log in to an PowerScale cluster through an SSH client and set the environment variable on the cluster through the isi ndmp settings variables create command.
