Problem
Backup Exec supports using NFS shares as backup-to-disk storage devices (B2D) via UNC path such as \\server-name\folder-name.
This document describes how to check an NFS share can be used as a B2D.
Error Message
N/A
Cause
Currently, there are no certified NFS devices. Customers can verify that an NFS device or NFS share can be used as a B2D.
Solution
1. Logon into Backup Exec server using Backup Exec Service Account (BESA).
2. Open a Command Prompt.
3. Go to Backup Exec installed folder:
C:\...> cd C:\Program Files\Veritas\Backup Exec
by default
4. Execute the following command:
C:\...> b2dtest -d -w \\server\folder
-d: (default) suppress inputting comments about the share or device.
-w: (working folder) Specify the UNC path of the NFS share which needs to be checked.
Limitations:
Simplified Disaster Recovery (SDR) does not support using NFS shares when recovering a Backup Exec server. Remote servers can be restored using active Backup Exec servers and NFS shares.
Backing up from NFS shares is not supported.
Example output of b2dtest command:
C:\Program Files\Veritas\Backup Exec>b2dtest -d -w \\storage1\nfs\export1

06/27/23 16:22:41 Build 22.0.1193
06/27/23 16:22:41
06/27/23 16:22:41 This tool can take up to several hours to complete. The
06/27/23 16:22:41 amount of time it takes is dependent on the host computer as
06/27/23 16:22:41 well as the underlying appliance technology. It is
06/27/23 16:22:41 recommended that this tool be run at a time when there will be
06/27/23 16:22:41 minimal impact on business operations.
06/27/23 16:22:41
06/27/23 16:22:41 For the tool to run successfully, the target location of the
06/27/23 16:22:41 test must contain at least 4,339,073,024 bytes of available
06/27/23 16:22:41 space. Furthermore, any credentials supplied must have
06/27/23 16:22:41 sufficient privileges to create, read, write, and delete
06/27/23 16:22:41 directories and files on the appliance.

06/27/23 16:35:38 Reparse Points - WARNING - Reparse points not supported on appliance: (0x32) The request is not supported.
06/27/23 16:35:38 The appliance does not support reparse points. Some
06/27/23 16:35:38 of the advanced B2D technologies such as GRT may not
06/27/23 16:35:38 function.
06/27/23 16:35:38
06/27/23 16:35:38 For GRT to function correctly, either the B2D path
06/27/23 16:35:38 or the temporary path for GRT operations must be an
06/27/23 16:35:38 NTFS partition that supports reparse points. If this
06/27/23 16:35:38 is not the case, GRT operations will fail.
