Non-vendor-specific information

Supported operating systems

The NetBackup operating systems compatibility lists provide the most up-to-date list of supported operating systems, with notes on supported hardware platforms. NDMP compatibility is listed as a column in the NetBackup Server section for each operating system in the compatibility list:

https://support.cohesity.com/s/article/article-100040093

Note:

NetBackup for NDMP is installed on a master or media server, not on a client.

NAS appliance versions

The information in this document may apply to many different NetBackup releases. To find if your device and its features are supported at a particular NetBackup level, refer to the NetBackup Hardware Compatibility List (HCL) for the version of NetBackup that you are running:

https://support.cohesity.com/s/article/article-100040093

Authorizing NetBackup access to the NDMP host

Use the tpconfig and tpautoconf commands as described under "Example Configuration Sequence" in each of the following sections of this document for particular NDMP hosts.

For NAS hosts that support Direct Access Recovery (DAR), NetBackup enables DAR by default.

About file restores to a different location

When restoring files from NetBackup backups of NAS filers that use older versions of the NDMP protocol (V2 and V3), the destination path for the restore must end with the original folder and file name, even if you are restoring the files to a different location. (This restriction does not apply to NAS filers that use the NDMP protocol V4.)

If the original backup path was /vol/vol1/mydir/myfile, the destination path for restore to a different location must end with /mydir/myfile. Otherwise, NetBackup appends /mydir/myfile to the end of the destination path.

For example, to restore /vol/vol1/mydir/myfile to a folder under/vol/vol2/, specify /vol/vol2/mydir/myfile as the destination.

For NAS filers that use NDMP V4, you can specify a different subfolder or file name. For example, /vol/vol1/mydir/myfilecan be restored to /vol/vol2/mydir2/myfile_restored.

For any restrictions unique to a particular NAS filer, see the appropriate section in this document for your filer.

About NDMP Environment Variables

The NDMP protocol specification uses environment variables to control backup and restore operations. These variables are defined by each vendor individually, with some amount of adherence to a common, defined set. NetBackup controls the setting of some of those variables without the ability for a user to change them (such as LEVEL and USER), and some of them are modified by NetBackup settings and policy configuration (such as DIRECT and FILESYSTEM). It is possible to change some of the variables in the include list of a NetBackup policy, such as variables for which NetBackup just passes a default value (HIST, TYPE) and for those variables that are vendor-specific.

With such a large set of possibly vendor-specific implementations of environment variables, it is impossible to provide an exhaustive list in this document. An attempt has been made to document those variables that were found during testing to have the most impact. Refer to vendor documentation for more information.
